Professor PC Thomas Classes · Answer

(a, b, d) :\(a)Compounds I and II are $1^{\circ}$ alkyl halides, then they undergo $\mathrm{S}_{\mathrm{N}} 2$ mechanism.\(b)Compound IV undergoes inversion of configuration due to intimate-ion pair formation, inversion predominates over retention.\ (c)Stability of carbocations follows the order:\ (d)I is a benzylic halide, thus, it undergoes $\mathrm{S}_{\mathrm{N}} 1$ reaction easily as benzylic carbocation is resonance stabilised. III also follows $\mathrm{S}_{\mathrm{N}} 1$ mechanism as it a $3^{\circ}$ alkyl halide.\
