In Aryl amines lone pair is in conjugation with double bond so basic strength decreased
While in aliphatic amine (R−NH2) no delocalisation of lone pair and +I effect of −CH3 group so they have more basic strength.

The correct statement regarding the basicity of aryl amines is:
Held on 30 Apr 2016 · Verified 9 Jul 2026.
Aryl amines are generally less basic than alkyl amines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic ring π electron system.
Aryl amines are generally more basic than alkyl amines because the nitrogen lone-pair electrons are not delocalized by interaction with the aromatic ring π electron system.
Aryl amines are generally more basic than alkyl amines because of aryl group.
Aryl amines are generally more basic than alkyl amines, because the nitrogen atom in aryl amines is sp-hybridized.

Which of the following is a reducing sugar?
Name the class of enzyme that usually catalyze the following reaction : $\mathrm{S}-\mathrm{G}+\mathrm{S}^{\#} \rightarrow \mathrm{~S}+\mathrm{S}^{\#}-\mathrm{G}$ Where, $G \rightarrow$ a group other than hydrogen $S \rightarrow$ a substrate $\mathrm{S}^{\#} \rightarrow$ another substrate
Identify the suitable reagent for the following conversion 
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : undergoes $\mathrm{S}_{\mathrm{N}} 2$ reaction faster than Reason (R) : Iodine is a better leaving group because of its large size. In the light of the above statements, choose the correct answer from the options given below :
