Q.
Among $ HF,CH_{4},CH_{3}OH$ and $N_{2}O_{4},$ inter molecular hydrogen bond is expected:

Solution:
$HF$ and $CH_{3}OH$ shows intermolecular hydrogen bonding. Hydrogen bonding is present between a highly electronegative element and hydrogen. Hence, $CH_{4}$ and $N_{3}O_{4}$ cant show hydrogen bonding.
