Question

2-Methyl propyl bromide reacts with C₂H₅O^- and gives 'A' whereas on reaction with C₂H₅OH it gives 'B'. The mechanism followed in these reactions and the products 'A' and 'B' respectively are

(1) S_N2. A iso-butyl ethyl ether; S_N1, B = tert- butyl ethyl ether

(2) S_N1, A = tert-butyl ethyl ether; S_N1, B = 2- butyl ethyl ether

(3) S_N1, A tert-butyl ethyl ether; S_N2, B = iso- butyl ethyl ether

(4) S_N2, A = 2-butyl ethyl ether; S_N2, B = iso- butyl ethyl ether

Answer 1

(1) S_N2. A iso-butyl ethyl ether; S_N1, B = tert- butyl ethyl ether
