Question

hydrogen bonds will form between a hydrogen atom in one molecule and which atom in another molecule?
all of the above
chlorine
nitrogen
sulfur

Explanation:

Hydrogen bonds form when a hydrogen atom (covalently bonded to a highly electronegative atom like N, O, F) interacts with a lone pair on another highly electronegative atom. Nitrogen is one of these atoms (along with O and F). Chlorine and sulfur have lower electronegativity and larger atomic size, so they do not form hydrogen bonds effectively. Thus, only nitrogen among the options qualifies.

Answer:

nitrogen
