Vedclass · Answer

(A) According to Lewis theory,a base is a species that donates a lone pair of electrons. In aniline,the lone pair on the nitrogen atom is involved in resonance with the benzene ring,making it less available for donation compared to the lone pair in $NH_3$. Therefore,$NH_3$ is a stronger base than aniline. Statement $(A)$ claims aniline is a stronger base than ammonia,which is false. Statement $(B)$ is true because methylamine is an aliphatic amine with an electron-donating alkyl group,making it more basic than aniline. Statement $(C)$ is true because a weaker base has a higher $pK_b$ value. Statement $(D)$ is true because aniline reacts with bromine water to form $2,4,6$-tribromoaniline,which appears as a white precipitate. Thus,the false statement is $(A)$.
