From the following list of substances, how many form extensive intermolecular hydrogen bonds in thei — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Hydrogen bonding requires H bonded directly to F, O, or N. The molecules that meet this criteria and form intermolecular H-bonds are $NH_3$, $HF$, $CH_3OH$, $C_2H_5OH$, and $CH_3COOH$. Molecules like $H_2S$ and $HCl$ lack sufficient electronegativity, and ethers ($CH_3OCH_3$) lack an $O-H$ bond. Total = 5.
