2. Write two methods for the preparation of alkane.

A. From Unsaturated Hydrocarbons:

Dihydrogen gas is added to alkenes and alkynes in the presence of finely divided catalysts like Pt,Pd, , or Ni to form alkanes. This process is called hydrogenation.


B. From Alkyl Halide:

Alkyl halides on treatment with sodium metal in a dry ethereal solution give higher alkanes. This reaction is known as the Wurtz reaction and is used for the preparation of higher alkanes containing an even number of carbon atoms.

3. What are the physical properties of alkanes?

A. Alkanes are nonpolar molecules because of the covalent nature of C-C and C-H bonds and due to very little difference in electronegativity between carbon and hydrogen atoms.

B. They possess weak van der Waals forces.

C. Due to the weak forces, the first four members, from  C1 to C4 are gases, C5 to C17 are liquids and those containing 18 carbon atoms or more are solids at 298 K.

D. They are colourless and odourless.

4. Do students have to give any details to download  class 11 chemistry chapter 13 NCERT?

NO, actually neither the official website of NCERT nor Vedantu will not ask for any details to download the NCERT Books.

5. What is pyrolysis?

When Higher alkanes are heated to higher temperatures, they decompose into lower alkanes, alkenes, etc. Such a decomposition reaction into smaller fragments by the application of heat is called pyrolysis. It is also known as cracking. It is believed that pyrolysis of alkanes follows fee radical mechanism. The preparation of oil gas or petrol gas from kerosene oil involves the principle of pyrolysis.
