Assertion: Basicity of and is in order I II III.
Reason: Electron-donating groups (such as alkyl group) increase the basicity of amines, and electron-withdrawing groups (such as aryl group) decrease the basicity of amines.
Reason: Electron-donating groups (such as alkyl group) increase the basicity of amines, and electron-withdrawing groups (such as aryl group) decrease the basicity of amines.
View answer and explanation
