4metyylifenyyli

4-Methylphenyl, also known as p-tolyl, is an organic chemical group. It consists of a benzene ring with a methyl group attached at the para position (position 4) relative to the point of attachment of the group to another molecule. The chemical formula for the 4-methylphenyl group is C7H7.

This group is a common substituent in organic chemistry and is found in a variety of compounds. For example, it is a component of toluene, which is methylbenzene. When toluene loses one hydrogen atom from its methyl group, it forms the 4-methylphenyl radical. This radical can then attach to other atoms or molecules.

Compounds containing the 4-methylphenyl group can exhibit diverse chemical and physical properties depending on the rest of the molecule. These properties influence their applications in various fields, including pharmaceuticals, dyes, and polymers. The presence of the methyl group can affect electron distribution within the aromatic ring, influencing its reactivity in chemical reactions. The para substitution pattern is distinct from ortho (position 2) and meta (position 3) substitution, leading to different spatial arrangements and potentially different properties.
