Vedclass · Answer

(D) The basic strength of amines depends on the availability of the lone pair on the nitrogen atom. $(A)$ $Ph-NH-Ph$ (diphenylamine) is very weak due to resonance with two phenyl rings. $Ph-NH_2$ (aniline) is weak due to resonance with one phenyl ring. Cyclohexylamine is a strong base because the lone pair is localized. The order is correct. $(B)$ Pyrrole is non-basic because the lone pair is involved in aromaticity. Pyridine is weakly basic ($sp^2$ hybridized). Piperidine is a strong secondary amine. The order is correct. $(C)$ $-NO_2$ is an electron-withdrawing group (decreases basicity),and $-CH_3$ is an electron-donating group (increases basicity). The order is correct. $(D)$ Pyrrole is non-basic. Pyrrolidine is a strong secondary amine. Imidazole is also basic. The order $Pyrrole > Pyrrolidine > Imidazole$ is incorrect because pyrrolidine is much more basic than pyrrole. Thus,option $D$ is not correct.

Which of the following is not correct regarding basic strength?
