Each\[N{{H}_{3}}\]molecule has six other\[N{{H}_{3}}\]molecules as nearest neighbours in solid state; AH of sublimation of \[N{{H}_{3}}\] molecule at the m. p is\[30.8\text{ }kJ\text{ }mo{{l}^{-1}}\]and in the absence of H-bonding estimated\[\Delta H\]of sublimation is\[14.4\text{ }kJ\text{ }mo{{l}^{-1}}\]. Hence, strength of H-bond in solid\[N{{H}_{3}}\]is

A)  \[5.47\text{ }kJ\text{ }mo{{l}^{-1}}\]                     

B)  \[\text{10}\text{.93 }kJ\text{ }mo{{l}^{-1}}\]

C)  \[\text{16}\text{.40 }kJ\text{ }mo{{l}^{-1}}\]                     

D)  \[\text{-16}\text{.4 }kJ\text{ }mo{{l}^{-1}}\]
