Benzylamine may be alkylated as shown in the following equation :
C₆H₅CH₂NH₂ + R—X → C₆H₅CH₂NHR
Which of the following alkylhalides is best suited for this reaction through SN1 mechanism?
Options:
Answer:
C
Solution:
An SN1 path requires a stable carbocation. C₆H₅CH₂Br ionises to the resonance-stabilised benzyl cation, so it reacts fastest by SN1. CH₃Br and C₂H₅Br form unstable 1° cations (SN2 only) and C₆H₅Br does not ionise (aryl C—Br).
