Vedclass · Accepted Answer

o-Toluidine > Aniline (Basic strength)

Vedclass · Answer

(B) Let's analyze each option:$A$: $o$-Nitrobenzoic acid is more acidic than benzoic acid due to the ortho effect,which is correct.$B$: $o$-Toluidine is less basic than aniline due to the Steric Inhibition of Protonation $(SIP)$ effect,which decreases the basic strength. Thus,the given order is incorrect.$C$: $(CH_3)_3C-O^-$ is less stable than $CH_3-CH_2-O^-$ because the electron-donating inductive effect $(+I)$ of the three methyl groups in the tert-butoxide ion increases the electron density on the oxygen atom,making it less stable. The order $(CH_3)_3C-O^- $D$: Methylenecyclohexane is less stable than $1-$methylcyclohexene due to the lack of hyperconjugation and resonance stabilization of the double bond. Therefore,it has a higher heat of hydrogenation. This order is correct.Since $B$ shows $o$-Toluidine $>$ Aniline,which is incorrect due to the $SIP$ effect,$B$ is the correct answer.
