Arrange the following compounds in decreasing order of their boiling points: NH3, HF, SiH4, CH4

A.

HF,NH3, SiH4, CH4

B.

CH4, SiH4, HF, NH3,

C.

NH3,CH4, SiH4, HF

D.

CH4, SiH4, NH3, HF

Correct answer is A

The correct order of boiling points of the compounds NH3, HF, SiH4, and CH4 is HF, NH3, SiH4, CH4.
The correct order of boiling points of the compounds NH3, HF, SiH4, and CH4 is HF, NH3, SiH4, CH4.

The boiling point of a compound is the temperature at which the vapor pressure of the liquid is equal to the atmospheric pressure. The stronger the intermolecular forces, the higher the boiling point.
