GATE CY 2025 CY Q52: Reaction Mechanisms

Consider the following two reactions and their corresponding Hammett plots

Reaction M: Ar–C(CH₃)₂Cl →[S_N1, slow, kₓ] Ar–C⁺(CH₃)₂ →[H₂O, kₓ] Ar–C(CH₃)₂OH Reaction N: Ar–COOEt + OH⁻ →[H₂O, kₓ] Ar–COO⁻ + EtOH

Choose the option(s) that correctly match(es) the points on the graph given in Column-I with substituents X given in Column-II in accordance with their substituents constant σ

Your answerSelect all correct options. You can choose more than one.

s → σ_(X = Cl); t → σ_(X = OMe); u → σ_(X = NH₂); r → σ_(X = NO₂)

s → σ_(X = Me); u → σ_(X = NH₂); t → σ_(X = OMe); r → σ_(X = Br)

p → σ_(X = Me); q → σ_(X = CN); r → σ_(X = NO₂); t → σ_(X = OMe)

p → σ_(X = Cl); q → σ_(X = NO₂); r → σ_(X = CN); t → σ_(X = Me)
