Question

20. Classify the following reactions as electrophilic, nucleophilic or free radical
substitution

(a) CH2Cl + OH - CH OH + CI
(b) CH4 + HNO₃ -C6H5NO2 + H2o​

Answer 1

Explanation:

a free radical substitution reaction

In organic chemistry, we encounter with various types of substitution reactions. One of them is a free radical substitution reaction.

Example: Halogenation of methane

$$CH_{4} + Cl_{2} \xrightarrow{h\nu} CH_{3}Cl+HCl$

This reaction goes through free radical intermediate.
