Class 11 Chemistry Revision Notes for Chapter 13 - Hydrocarbons - Free PDF Download

To make studying more fun and easy, the CBSE revision notes for class 11 Chemistry chapter 13 hydrocarbons are available from the Vedantu site for free download. Students can also refer to these PDF notes, which contain a detailed explanation for all the important chapter topics. Using these PDF notes will enable the students to understand every topic clearly and come out with flying colors in the exams.

When we speak about the hydrocarbons in chemistry, they can be explained as organic compounds composed of hydrogen and carbon elements. However, when we study this topic in class 11, which is found in the CBSE books of chapter 13, we need to learn about various things such as the classification of hydrocarbons, alkenes, alkanes, alkynes, toxicity, and carcinogenicity, and understand the equations as well, solving different problems, and many more.

Revision Notes for Class 11 Chemistry Chapter 13 - Hydrocarbons

Class 11 Hydrocarbons Revision Notes

This complete article deals with class 11 hydrocarbons revision notes. Firstly, the term ‘hydrocarbons’ refers to the compounds of hydrogen and carbon only. Hydrocarbons specifically play a crucial role in our lives. 

Moreover, humans obtain kerosene, diesel, and petrol by the fractional distillation of petroleum. In the same way, humans also obtain coal gas by the destructive distillation of coal. All such fuel types, which are the sources of energy, comprises hydrocarbons mixture.

One of the most important alkenes reactions certainly happens to be oxidization, combustion, aromatization, and free radical substitution. Moreover, alkynes and alkenes undergo different multiple reactions. Most notably, these reactions are of addition reactions, which are electrophilic additions mainly. Also, the aromatic hydrocarbons primarily undergo electrophilic substitution reactions despite having unsaturation.


Topics Covered Under Class 11 Chemistry

Some of the topics that fall under the Class 11 Chemistry include:

  • Some basic concepts of Chemistry

  • Classification of the Elements & Periodicity in Properties

  • Structure of Atom

  • States of Matter - Liquids and Gases

  • Chemical Bonding & Molecular Structure

  • Equilibrium

  • Thermodynamics

  • Redox Reactions

  • Hydrocarbons

  • Environmental Chemistry (Not for Examination point of View)


Sub-Topics Covered Under Hydrocarbons

  • Alkanes - Alkanes are known as organic compounds that consist of only hydrogen and carbon atoms which are single-bonded

  • Conformation of Alkanes - The conformation of alkanes deals with the isomers of alkanes whose formation is due to the slight structural changes

  • Preparation of Alkenes and Nomenclature - This basically deals with the preparation of the Alkenes and its naming

  • Preparation of Alkynes and Nomenclature - Naming of Alkynes occurs by counting the longest continuous chain’s number of carbons, and their preparation is mostly the same as those of the alkenes

  • Preparation of Aromatic Hydrocarbons and Nomenclature - According to the IUPAC system, the naming of aromatic hydrocarbons happens as benzene derivatives. In contrast, their preparation happens by different methods, and the most common method used is the isolating coal tar.

  • Properties of Alkanes - Alkanes are known to be the unsaturated form of hydrocarbons

  • Properties of Alkynes - Alkynes are the third type of hydrocarbon which contains at least one triple bond between a pair of carbon atoms

  • Properties of Aromatic Hydrocarbons - The aromatic Hydrocarbons are called cyclic hydrocarbons having the delocalized pi electrons between the carbon atoms of the ring

FAQs on Hydrocarbons Class 11 Notes CBSE Chemistry Chapter 13 [Free PDF Download]

1. What are CNG and LPG?

CNG 

CNG (Compressed Natural Gas) mainly consists of methane (95%), a relatively unreactive hydrocarbon, and makes its nearly complete combustion possible.


LPG

LPG (Liquified Petroleum gas) is a mixture of isobutane and butane containing a small amount of propane. A strong, foul-smelling substance, known as ethyl mercaptan (C2H5SH), is added to the LPG cylinders, detecting the gas leakage.

2. Mention some important points in terms of Hydrocarbons?

Some important points of Hydrocarbons concerning Alkanes can be given as follows.

  • Alkenes are more reactive when compared to Alkanes. This is because of the availability of n electrons.

  • The double bond of carbon-carbon in alkenes is composed of one σ-bond and one π-bond.

3. Explain the classification of Hydrocarbons?

The classification of Hydrocarbons can be depicted clearly with the following representation.

(Image to be added soon)

Students can get a clear understanding by pointing to this pictorial representation at the time of their exams, without any doubt, and can be remembered easily.

4. Explain the importance of revision notes?

Revision Notes are much important for every student because:

  • All the important points will be found regarding the complete chapter in the notes

  • It is easy to carry the revision notes because the size of it is handy

  • Since the students will note the formulas, points to remember, and more related, there is a less possibility of performing the to-do list at the time of exams.

5. Why should we refer to Revision Notes for Class 11 Chemistry Chapter 13?

As Chemistry is a challenging topic, you must practice it as much as possible. In addition, the Class 11 Chemistry Chapter 13 Revision Notes are well-structured and correspond to the CBSE syllabus for Class 11. Going through these notes is important since they cover a wide range of topics and concepts, giving you a solid idea of all the concepts covered in the chapter. As a bonus, these questions teach you how different questions on the same topic may be set. The revision notes can also be downloaded free of cost.

6. What are the topics covered in the Class 11 Chemistry Chapter 13 Revision Notes?

This chapter contains topics related to hydrocarbons such as contents on its classifications. Furthermore, the chapter contains content on alkanes, their nomenclature, isomerism, preparation and so on. Double bond structure, preparation, and isomerism of alkenes are also discussed in this chapter along with the preparation and properties of the triple bond of the alkyne groups. Similar properties are discussed for the groups of aromatic hydrocarbons. Few more topics related to hydrocarbons have been included in this chapter.

7. What are the 4 types of hydrocarbons?

Hydrocarbons are of two types - aliphatic and aromatic hydrocarbons. Alkanes, alkenes, and alkynes are aliphatic hydrocarbons. Benzene is an aromatic hydrocarbon. In general, hydrocarbons are composed of the following compounds: butane, propane, ethane, and methane. Four kinds of hydrocarbons exist. These are alkanes, alkenes, alkynes, and aromatic hydrocarbons (also known as hydrocarbons). Among hydrocarbons, the simplest ones are alkanes. Proper knowledge of all the types of hydrocarbons is important to get an overall idea of their properties and preparation processes and can be accessed through the Vedantu app.

8. Is Chapter 13 “Hydrocarbons” important for JEE?

For the JEE exam, you have to grasp the essential chemical concepts of hydrocarbon name and numbering, reactions with hydrocarbons, and alcohol reactions as well as carboxylic acid reactions with ketones. Hydrocarbons are very important for JEE’s chemistry section and multiple questions will be asked from this part. If you want to score well in your JEE exam, you must practice this chapter judiciously.

9. Does coal have adverse effects?

Combustion of coal produces several significant emissions, including a lot of sulphur dioxide. As a result of nitrogen oxides, smog and respiratory diseases can develop. There are particles in the air that are responsible for the creation of smog, haze, respiratory diseases, and lung disease. Each one of coal's consequences has an economic cost, from the loss of jobs for fishermen living downstream of a coal mine to the health care expenditures for those affected by coal-fired power plant pollution etc.
