Question

Why is a double bond stronger than a single bond?

Answer 1

Double Bond:

• The two atoms contain two pairs of electrons, generating a double bond.
• Because of its greater reactivity than a single bond, this form of connection is stronger than a single bond but less stable.
• A double bond between two atoms is represented by the symbol double lines $=$ (i.e., involving two electron pairs).
• Examples of molecules having double bonds are ${\mathrm{O}}_2,{\mathrm{CO}}_2$, etc.

Reason for a double bond stronger than a single bond:

• A double or triple bond is stronger than a single bond because it holds the atoms closer together and makes it more difficult to break.
• So, a double bond requires more energy to break the bonds as compared to a single bond.

Hence, a double bond is stronger than a single bond.
