Chapter 11, Problem 55E

Interpretation Introduction

(a)

Interpretation:

Among ${\text{H}}_{\text{2}}\text{O}$ and ${\text{H}}_{\text{2}}\text{S}$, the compound having higher melting point is to be stated.

Concept introduction:

The melting point of a compound is the temperature at which solid converts into liquid form. Melting point depends upon the intermolecular forces of attraction between the molecules and is also directly proportional to the molar mass of the compound.
