Question

Where is dative bond not involved?

• A. Protonation of ether
• B. Dissolution of $HF$ in water
• C. Dimerisation of benzoic acid
• D. Formation of ${Be}_2{Cl}_4$

Answer 1

Answer: (B), (C)

The correct options are
B Dissolution of $HF$ in water
C Dimerisation of benzoic acid

Dative bond is not involved in dimerisation of benzoic acid. Dimerisation of benzoic acid involves intermolecular H-bonding. Also, a H-bond exists between $H$ and $F$.

In protonation of ether, a dative bond exists between $O$ of ether and $H^{+}$ of water molecules. In $BeC{l}_2$, a dative bond exists.
