`HF`

`NH_3`

`H_2Te`

Text Solution

Verified by Experts

The correct Answer is:

The correct order of boiling points is `H_2OgtHFgtH_2TegtNH_3`
It may seem odd at first that the boiling point of HF is lower than that of water. Fluorine is more electronegative than oxygen, and so we would expect a stronger hydrogen bond in liquid HF than in `H_2O`. But `H_2O` is unique in that each molecule takes part in four intermolecular H bonds, and the `H_2O` molecules are, therefore, held together more strongly.
