    The energy of hydrogen bond is of the order of:

    A) \[4KJ mo{{l}^{-1}}\]               

    B) \[40KJ mo{{l}^{-1}}\]

    C) \[400KJmo{{l}^{-1}}\]             

    D) \[4000 KJ mo{{l}^{-1}}\]

    Correct Answer: B

    Solution :

    \[\mathbf{40KJ}\text{ }\mathbf{mo}{{\mathbf{l}}^{-1}}\] The strength of hydrogen bond is very small for example strength of H...F is\[41.8KJ mo{{l}^{-1}}\]. It involves dipole - dipole attractive interactions.
