2-Methyl propyl bromide reacts with $$\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{O}^{-}$$ and gives 'A' whereas on reaction with $$\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}$$ it gives 'B'. The mechanism followed in these reactions and the products 'A' and 'B' respectively are :

A
$$\mathrm{S}_{N} 1, A=$$ tert-butyl ethyl ether; $$\mathrm{S}_{N} 2, B=$$ iso-butyl ethyl ether
B
$$\mathrm{S}_{\mathrm{N}} 1, \mathrm{~A}=$$ tert-butyl ethyl ether; $$\mathrm{S}_{\mathrm{N}} 1, \mathrm{~B}=$$ 2-butyl ethyl ether
C
$$\mathrm{S}_{\mathrm{N}} 2, \mathrm{~A}=$$ iso-butyl ethyl ether; $$\mathrm{S}_{\mathrm{N}} 1, \mathrm{~B}=$$ tert-butyl ethyl ether
D
$$\mathrm{S}_{\mathrm{N}} 2, \mathrm{~A}=$$ 2-butyl ethyl ether; $$\mathrm{S}_{\mathrm{N}} 2, \mathrm{~B}=$$ iso-butyl ethyl ether
