Answer:
Structure of meta xylene has been shown below.
Step-by-step explanation:
- Xylene is dimethyl substituted benzene.
- Among three possible isomers of xylene, only meta substituted xylene gives mononitration product at two different position.
- Mononitration is possible in meta-xylene due to synergistic effect of two o/p-orienting methyl groups.
- Synergistic effect refers that o/p-directing power of two methyl groups act together at a particular position.
- Structure of xylene as well as their two possible mononitro derivatives has been shown below.
