Question

What is substution reaction? Give example

Answer 1

When a elements like chlorine replace a hydrogen or group of hydrogen atoms from its compound then the reaction is called substitution reaction .

Example:Ch4 + Cl2 ( chlorine) ---> CH3Cl + HCL ( in presence of sunlight)

Answer 2

The reaction in which the place of one type of atom/group in a reactant is taken by another atom/group of atoms, is called substitution reaction. Chlorination of methane, is a substitution reaction which gives four products.

CH4 + Cl2 = CH3 - Cl + HCL

CH3 CL + Cl2 = CH3 CL2 + HCL

CH3 CL2 + Cl2 = CHCL3 + HCL

CHCL3 + Cl2 = CCl4 + HCl

Still larger number of products are formed in chlorination reaction of higher homologous of alkane.

( = in presence of sunlight )
