(a)
Interpretation:
The number of potential H-bond donors and H-bond acceptors present in the given molecules are to be determined.
Concept introduction:
An H-bond donor is an H atom which is covalently bonded to a strongly electronegative atom such as N, O, or F and the H-bond acceptor is the neighboring electronegative ion or molecule which must possess a lone pair of electrons.
