- Formula: C6H5-CH2-CH3.
- Properties: Commonly used as a solvent and in the production of styrene.
2. Styrene (Vinylbenzene)
- Structure: A benzene ring with a vinyl group (C2H3).
- Formula: C6H5-CH=CH2.
- Properties: Important in the production of polystyrene, a widely used plastic.
3. 1,2-Dimethylbenzene (Ortho-xylene)
- Structure: A benzene ring with two methyl groups (C2H6) located on adjacent carbons.
- Formula: C6H4(CH3)2.
- Properties: Used as a solvent and in the manufacture of various chemicals.
4. 1,3-Dimethylbenzene (Meta-xylene)
- Structure: A benzene ring with two methyl groups on the 1 and 3 positions.
