TestHub · Accepted Answer

The reaction between methyl propyl bromide and $C_{2} H_{5} O^{-}$ proceeds via an $S_{N} 2$ (substitution nucleophilic bimolecular) mechanism. In this mechanism, the nucleophile attacks the carbon atom bearing the bromine (the electrophilic carbon) in a single step, leading to the displacement of the bromine atom.

The reaction between methyl propyl bromide and $C_{2} H_{5} OH$ can proceed via either an $S_{N} 1$ (substitution nucleophilic unimolecular). Here $C_{2} H_{5} OH$ is a weak nucleophile. During the reaction 1,2-hydrogen shift will occur and tert-butyl ethyl ether is formed.
