E) nitrogen, fluorine, oxygen, or nitrogen.

Question

Quizplus · Accepted Answer

Hydrogen bonding occurs when hydrogen is covalently bonded to elements with high electronegativity such as fluorine, oxygen, or nitrogen. This is because these elements have strong partial charges (δ-) that are attracted to the partial positive charge (δ+) on the hydrogen atom. Chlorine and iodine are not electronegative enough to participate in hydrogen bonding, while sulfur also has a relatively low electronegativity.
