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) \[\text{-16}\text{.4 }kJ\text{ }mo{{l}^{-1}}\]
Correct Answer: A
Solution :
Total strength of all H-bonds \[=30.8-14.4\] \[=16.4kJ\,mo{{l}^{-1}}\] There are six nearest neighbours, but each hydrogen bond involves 2 molecules. Hence, effective neighbours = 3 Hence, strength of H-bond \[=\frac{16.4}{3}=5.47\,kJ\,mo{{l}^{-1}}\]You need to login to perform this action.
