The correct order for acid strength of compounds CH ≡ CH , CH 3 - C ≡ CH and CH 2 = CH 2 is as follows:

HC ≡ CH > CH 3 - C ≡ CH > CH 2 = CH 2

CH 3 - C ≡ CH > CH ≡ CH > CH 2 = CH 2

CH ≡ CH > CH 2 = CH 2 > CH 3 - C ≡ CH

CH 2 - C ≡ CH > CH 2 = CH 2 > HC ≡ CH

The correct statement regarding the basicity of aryl amines is:

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.
