Identify the compound with the highest boiling point. A) CH₄ B) PH₃ C) HCl D) H₂Se E) H₂O

Question

Quizplus · Accepted Answer

The compound H₂O has the highest boiling point due to its hydrogen bonding. Hydrogen bonding occurs between the hydrogen atom of one molecule and the oxygen atom of another molecule. This leads to strong intermolecular forces and a high boiling point. The other compounds do not have hydrogen bonding and therefore have weaker intermolecular forces, resulting in lower boiling points.
