The product obtained on chlorination of ...

The product obtained on chlorination of n-butane will be: `H_(3)C -CH_(2) - underset(Cl)underset(|)CH-CH_(3)`

A

meso-form

B

racemic mixture

C

d-form only

D

I-form only

Text Solution

Verified by Experts

The correct Answer is:
B
Chlorination of alkanes is a free radical substitution.
`CH_3CH_2CH_2CH_3overset(Cl_2)toCH_3CH_2CH(Cl)CH_3`
Since the intermediate free radical is planar `(sp^2- "hybridized")`, it can be attacked on either side of the face forming two equantiomers in equal amounts. Hence, the product formed is a racemic mixture.
