Q.
2-Methyl propyl bromide reacts with $C_{2} H_{5} O^{-}$ and gives 'A' whereas on reaction with $C_{2} H_{5} OH$ it gives 'B'. The mechanism followed in these reactions and the products 'A' and 'B' respectively are: [2023]

Solution

Q.
2-Methyl propyl bromide reacts with $C_{2} H_{5} O^{-}$ and gives 'A' whereas on reaction with $C_{2} H_{5} OH$ it gives 'B'. The mechanism followed in these reactions and the products 'A' and 'B' respectively are: [2023]

1 $S_{N} 2, A = 2 - butyl ethyl ether; S_{N} 2, B=iso-butyl ethyl ether$

2 $S_{N} 2, A = iso - butyl ethyl ether; S_{N} 1, B = tert - butyl ethyl ether$

3 $S_{N} 1, A = tert - butyl ethyl ether; S_{N} 2, B = iso - butyl ethyl ether$

4 $S_{N} 1, A = tert - butyl ethyl ether; S_{N} 1, B = 2 - butyl ethyl ether$
