NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyThe correct statement regarding the basicity of arylamines is:
| 1. | Arylamines are generally more basic than alkylamines because the lone-pair electrons of nitrogen are not delocalized by interaction with the aromatic ring π-electron system. |
| 2. | Arylamines are generally more basic than alkylamines because of the aryl group +I effect. |
| 3. | Arylamines are generally more basic than alkylamines because the nitrogen atom in arylamines is sp-hybridized. |
| 4. | Arylamines are generally less basic than alkylamines because the nitrogen lone-pair electrons are delocalized by interaction with the aromatic ring π-electron system. |
