CANDIDATE ANSWER
Q. No
and
which alkyl halide from following pair is chiral
undergoes faster SN2 reaction
​

Answer 1

Answer:

The secondary alkyl halide 2-bromobutane is chiral and undergoes faster S N 1 reaction. The chiral carbon atom is marked with asterik. The chiral carbon atom is carbon atom with four different atoms or groups of atoms.

The primary alkyl halide (option a) 1-bromobuane is achiral and undergoes faster SN 2 reaction.

S N 2 reaction gives inversion of configuration.

S N 1 reaction gives racemisation.

Answer 2

Answer:

2- bromobutane is chiral
