The molecular mass of acetic acid $(CH_3COOH)$ dissolved in water is $60$,whereas when dissolved in benzene,it is $120$. This difference in behavior is because:
- AAcetic acid undergoes dissociation in water and association in benzene.
- BAcetic acid undergoes association in water and dissociation in benzene.
- CAcetic acid remains unaffected in both solvents.
- DAcetic acid undergoes dissociation in both solvents.
