MCQ

To carry out above conversion, $(A)$ and $(B)$ respectively, are

A
$NaNH_2 ,Cl - CH_2 - CH_2 - CH_2 -Br$
B
$NaNH_2 , F-CH_2 -CH_2 -CH_2 -Br$
✓
$NaNH_2 , I - CH_2 -CH_2 -CH_2 -Br$
D
$NaNH_2 , I-CH_2 -CH_2 -CH_2 -I$

✓

Answer

Correct option: C.

$NaNH_2 , I - CH_2 -CH_2 -CH_2 -Br$

c
$(c)$ Acid-base reaction follower by $S_{N^2}$
$\therefore$ $I$ is better leaving group than $Br$.
$\therefore$ $(c)$ is favourable.
