$CH_3COOH$

Vedclass · Answer

(A) Acetic acid $(CH_3COOH)$ exists as a dimer in the vapor phase and in non-polar solvents due to intermolecular hydrogen bonding. Two molecules of acetic acid are held together by two hydrogen bonds to form a cyclic dimer structure. $o$-nitrophenol exhibits intramolecular hydrogen bonding,which prevents dimerization. $AlCl_3$ exists as a dimer $(Al_2Cl_6)$ due to coordinate covalent bonding,not hydrogen bonding.
