Question

pyrolysis of alkanes is what type of reaction
1. nucleophilic addition reaction
2 free radical substitution reaction
3. electrophilic addition reaction
4. free radical elimination reaction

Answer 1

Hi friend,

First of all "Pyrolysis" (or) "cracking of alkane is one of a chemixal properties of alkanes.

The pyrolysis is meant by reducing the higher alkanes to lower alkanes by heating .

It mainly involves the free radicals movement and it comes under " FREE RADICAL MECHANISM ".

The correct answer is option (2).

Hope this helps you a little!!!

Answer 2

Pyrolysis of alkanes is a free radical elimination reaction.

• Pyrolysis of an alkane is a type of reaction where a higher member alkane is converted to a lower alkane.
• Thus in this reaction animation of some molecule occurs.
• This reaction proceeds through the free radical formation and elimination reaction so, pyrolysis of alkanes is a free radical elimination reaction.
• Hence the correct answer is 4.
