    Option C is correct answer

    eduncle-logo-app

    Due to ortho effect 4th one has least basicity

    eduncle-logo-app

    At meta position only inductive effect +I of methyl group works and at para position both inductive and resonance effect works

    eduncle-logo-app

    So IInd one is most basic

    eduncle-logo-app

    So overall basicity is 2>3>1>4

    eduncle-logo-app

    got it??

    eduncle-logo-app

    sir why 4th one has least basicity??

    eduncle-logo-app

    Do you read about ortho effect/SIP ..Due to this effect the the basicity of aniline decreases
