obtained by chlorination of n-butane, will be

A

meso form

B

racemic mixture

C

d-form

D

I-form

Answer

racemic mixture

Explanation

Solution

Chlorination of n-butane takes place by free radical mechanism are as follows: Step I Cl2→   Cl∙+Cl∙Cl_2 \rightarrow \, \, \, _{Cl}^{\bullet}+_{Cl}^{\bullet} Step II CH3CH2CH2CH3+CI∙→CH_3CH_2CH_2CH_3 + _{CI}^{\bullet} \rightarrow \hspace20mm CH_3 \, _{C}^{\bullet} HCH_2CH_3+HCI
