Ethane, CH 3 CH 3 , is a gas at room temperature, whereas ethanol, CH 3 CH 2 OH, is a liquid. Why the difference?

Interpretation Introduction

Interpretation:

The reason behind ethane being gas and ethanol being liquid at room temperature is to be explained.

Concept Introduction:

A molecule can be a gas or a liquid depending upon the intermolecular forces that exist between them. Hydrogen bonding takes place between those molecules which contain an electronegative atom, like N, O, and F, to which a hydrogen atom is attached.

Explanation of Solution

Those molecules which form strong hydrogen bonds exist as liquid, as in the case of ethanol. The ethane molecules form weak Van der Waals forces with the other ethane molecules because they has no electronegative atoms, which have the tendency to form hydrogen bonds. Therefore, it cannot form hydrogen bonds...
