Answer 2

"Hydrogen bonding occurs between (i) hydrogen and chlorine (ii) hydrogen and fluorine (iii) hydrogen and nitrogen"

( a) $CH_3 COOH$ and $C_2H_6$: Acetic acid $CH_3 COOH$  shows hydrogen bonding.

(b) $PH_3$ and $NH_3$: Ammonia $NH_3$  shows hydrogen bonding.

(c) Ortho nitrophenol and meta nitrophenol : Ortho nitrophenol show intramolecular hydrogen bonding whereas meta nitrophenol show intermolecular hydrogen bonding.

(d) HF and HCl : Hydrofluoric acid HF shows hydrogen bonding.

(e) $C_2H_5OH$ and $CH_4$:  $C_2H_5OH$  shows hydrogen bonding.
