Question

Match the compounds/reactions in List 1 with their mechanism in List 2. Matching can be one or more than one.

Answer 1

As $S_{N}1$ and $E_1$ are unimolar reactions while $S_{N}2$ and $E_2$ are Bimolar reactions so
(a) follows $S_{N}2$ mechanism while b follows $S_{N}1$ mechanism due to resonance.
(c) follows $E_{1}cb$ due to strong base $Ph{O}^{-}$ while
(d) follows $E_1$ mechanism in presence of alc. $KOH$ while
(e) follows $E_2$ mechanism in presence of alc. $KOH$
