Brief on Topics in "Hydrocarbons" for NEET 2025:

1. Alkanes:

Explore alkanes with a focus on nomenclature, isomerism, and ethane's conformations. Understand their physical properties and delve into chemical reactions, including the free radical mechanism of halogenation, combustion, and pyrolysis.

2. Alkenes:

Learn about alkenes, covering nomenclature, the structure of ethene, and geometrical isomerism. Understand physical properties and methods of preparation. Explore chemical reactions like hydrogenation, halogenation, and ozonolysis, and grasp the mechanism of electrophilic addition.

3. Alkynes:

Discover alkynes, exploring nomenclature, the structure of ethyne, and physical properties. Delve into methods of preparation and chemical reactions, emphasizing the acidic character of alkynes and addition reactions involving hydrogen, halogens, hydrogen halides, and water.

4. Aromatic Hydrocarbons:

Introduce aromatic hydrocarbons, covering IUPAC nomenclature and the structure of benzene. Understand resonance and aromaticity, and explore chemical properties, focusing on electrophilic substitution mechanisms like nitration, sulphonation, halogenation, Friedel-Craft’s alkylation, and acylation. Consider the directive influence of functional groups in mono-substituted benzene and delve into the carcinogenicity and toxicity aspects.

Important Questions from Hydrocarbons

1. What is the significance of resonance in benzene?

Ans. Resonance in benzene helps stabilize its structure, making it less reactive. The electrons are shared equally among carbon atoms, contributing to its stability and aromatic nature.

2. Explain the difference between alkanes and alkenes.

Ans. Alkanes are saturated hydrocarbons with single bonds, while alkenes are unsaturated with at least one double bond. Alkenes are more reactive due to the presence of the double bond.

3. How does the free radical mechanism work in halogenation of alkanes?

Ans. During halogenation, a free radical (unpaired electron) breaks the carbon-hydrogen bond, forming alkyl radicals. These radicals react with halogen molecules, leading to the substitution of hydrogen with a halogen atom.

4. What is the Markovnikov's addition rule in alkene reactions?

Ans. According to Markovnikov's rule, in the addition of hydrogen halides to alkenes, the hydrogen atom attaches to the carbon with more hydrogen atoms, while the halogen goes to the carbon with fewer hydrogen atoms.

5. Describe the acidic character of alkynes.

Ans. Alkynes exhibit acidic character due to the presence of the triple bond. The hydrogen in alkynes can be replaced by metal ions in a reaction, demonstrating their acidic nature.

6. What role does Friedel-Craft's alkylation play in aromatic hydrocarbons?

Ans. Friedel-Craft's alkylation involves adding an alkyl group to an aromatic ring. It is a key method for synthesizing substituted aromatic compounds, expanding the range of organic molecules.

7. Why is benzene considered carcinogenic and toxic?

Ans. Benzene exposure is linked to cancer risks and toxicity. Prolonged contact can damage bone marrow and affect blood cell production, posing health hazards. Avoiding prolonged exposure is crucial due to these potential health risks.

FAQs on NEET 2025 Chemistry Hydrocarbons Important Questions

1. How important is the Hydrocarbon chapter for the NEET examination?

Hydrocarbon is a very important topic to be covered for the NEET examination. It is a part of Organic Chemistry. It is about the chemistry of carbons and their compounds. It mostly deals with organic reactions which are very easy to understand but extremely difficult to remember. Every year on an average 30%-36% of questions in the Chemistry section are asked from the organic chemistry part. Thus it becomes very important for students to prepare for this topic as thoroughly as possible. Vedantu provides free and easy access to study material for students. You can download the NEET important questions PDF for free anytime and anywhere from Vedantu.

This question bank is freely available on Vedantu's website as well as on the mobile application in the form of free study material. These materials should be used to the fullest by the students.

3. How does one study Hydrocarbons in Chemistry for NEET to maximize their score?

Hydrocarbons topic for NEET can be prepared from Class 11 and Class 12 Chemistry NCERT textbooks. One should practice all the equations, IUPAC names, structures, and physical property-related questions from these books. This helps in building a strong base for organic chemistry. Most of the time questions asked in the NEET exam are basic. For a few advanced-level questions, you can refer to books available in the market. Choose a book as per your satisfaction. Take as many mock tests as possible. This will put you in examination mode.

4. Is it possible to tackle Chemistry without studying hydrocarbons?

Chemistry consists of three sections namely - Physical chemistry, Inorganic Chemistry, and Organic Chemistry. Hydrocarbons are an important sub-section of Organic Chemistry. It comprises a major syllabus of Chemistry i.e. almost ⅓ rd. Not studying organic chemistry involves risking 1/3rd of your marks. It’s recommended at least to cover basic NCERT textbooks of Class 11 and Class 12 for Hydrocarbons. Hydrocarbons constitute a part of the syllabus even in the higher standards when you will study Applied Chemistry. Thus, it is not possible to skip hydrocarbons and perform well in chemistry.

5. Can I study the Hydrocarbons topic in 2 days?

It is practically not possible to study Hydrocarbons in 2 days. Even if you succeed you will not be able to retain the studied information such as reactions and structures. Hydrocarbon is a topic that requires a lot of patience and practice. It should be studied slowly, one day at a time. Break down the syllabus into smaller sections and give enough time to each topic. Since a lot of o reactions get repeated, towards the end try to establish relations between different topics. Daily practice IUPAC names and molecular structures. Understand physical properties conceptually and logically. Emphasize more on name reactions. These baby steps taken from day 1 will fetch you results towards the end.
