Question

Multiple covalent bonds exist in a molecule of:F2 N2 CH4 H2

Answer 1

Answer: Option (b) is the correct answer.

Explanation:

A covalent bond is defined as the bond formed due to sharing of electrons between the combining atoms.

When only single bond exists due to sharing of electrons then it is known as a single covalent bond or covalent bond.

But when a double or triple bond exists between the combining atoms due to sharing of electrons then it is known as multiple covalent bond.

For example, in $N_{2}$ molecule there exists a triple bond between the nitrogen atoms.

Whereas in $F_{2}$, $CH_{4}$, and $H_{2}$ there exists only single bond between the combining atoms.

Thus, we can conclude that $N_{2}$ is the molecule in which multiple covalent bonds exist.
