Question

The molecular interactions responsible for hydrogen bonding in $HF$ is:

• A. ion-induced dipole
• B. dipole-dipole
• C. dipole-induced dipole
• D. ion-dipole

Answer 1

Answer: (B)

dipole-dipole

The molecular interactions responsible for hydrogen bonding in $HF$ are dipole-dipole interactions.
Note: $HF$ is a polar molecule. It can be represented as a dipole.
$H^{\delta +}-F^{\delta -}$
