Answer to Question #10242 in Physical Chemistry for Leah

Question

Which compound has molecules that form the strongest hydrogen bonds

Answer 1

The strongest hydrogen bonds are formed between molecules in which hydrogen is
covalently bonded to an element with high electronegativity and small atomic
radius, such as F in HF. or O in H2O. The small radius of F or O gives a
stronger attraction between the positive nucleus and the shared pair of
electrons between the non metal and the Hydrogen atom, thus making the positive
nucleus on the hydrogen able to exert its positive charge more strongly toward a
neighboring molecule.
