One after the other, examine methanol dimer and acetic acid dimer. Do the hydrogen-bond lengths in these systems differ significantly from the optimum distance in water dimer Are the hydrogen-bond angles in these compounds significantly different from those in water dimer Rationalize your results. 

Because the carboxylic acid functional group is structurally related to both ketones and alcohols, we might expect to see some familiar properties. Like ketones, the carboxyl carbon has sp hybridization, and carboxylic acid group.s are therefore p anar with C-C=0 and 0=C-0 bond angles of approximately 120°. The physical parameters of acetic acid are given in Table 20.2. 

Give the approximate values of angles a, b, c and d between the bonds in acetic acid ...
