Methyl Group vs. Methylene Group: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 12, 2024
A methyl group is a -CH₃ group, a carbon atom bonded to three hydrogens. A methylene group is a -CH₂- group, a carbon atom bonded to two hydrogens and attached to other atoms or groups.

Key Differences

A methyl group, -CH₃, consists of one carbon atom bonded to three hydrogen atoms. In contrast, a methylene group, -CH₂-, features a carbon atom bonded to two hydrogen atoms and connected to other carbon atoms or groups.
