Question

Put the following in order in terms of increasing melting point: SiH4, SiO2, CH4, NH3, PH3.

Lowest → Highest
(A) NH3, PH3, CH4, SiH4, SiO2
(B) SiO2, PH3, NH3, CH4, SiH4
(C) SiH4, CH4, NH3, PH3, SiO2
(D) CH4, SiH4, PH3, NH3, SiO2
(E) CH4, SiH4, SiO2, NH3, PH3
We would be interested in your thoughts and why you have them arranged in that order.
