Question

which of the molecules listed below can form hydrogen bond? For wich of the molecules would dispersion forces be the only intermolecular force? Give reasons for answer.
A.H2
B.NH3
C.HCl
D.HF

Answer 1

H bonds are formed in molecules with N, O, or F as the central atom and containing H atoms attached. So NH3, HCl, and HF are capable of forming H bonds. H2 is a homomolecule and will have only dispersion forces.

Answer 2

HF is the hydrogen bond in the listed below because hydrogen must be bonded to either a fluorine,oxygen or nitrogen atom.
