Assertion : Benzyl amine is less basic than ethyl amine. Reason : Benzene shows $+I$-effect.

  • A

  • Correct answer
    C
    If assertion is true but reason is false.
  • D
    If both assertion and reason are false.

$\mathrm{PhCH}_2 \mathrm{NH}_2$ (Benzyl amine) has $-I$-effect of phenyl group while $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{NH}_2$ has $+I$-effect of ethyl group.
