Question

H2, N2, O2 and Li2 are ______________

(a) heteronuclear diatomic molecules

(b) heteronuclear triatomic molecules

(c) homonuclear diatomic molecules

(d) homonuclear triatomic molecules

I have been asked this question in semester exam.

This key question is from Bonding in Some Homonuclear Diatomic Molecules topic in portion Chemical Bonding and Molecular Structure of Chemistry – Class 11

Answer 1

The correct option is (c) homonuclear diatomic molecules

Explanation: The molecules that have the same atoms in them are called as homonuclear molecules. The molecules that have only two atoms are called diatomic molecules. So H2, N2, O2, and Li2 are called homonuclear diatomic molecules.
