The correct answer is m-Xylene.

Key Points

• 1,3-Dimethylbenzene:-
  • It is also known as "meta-xylene" or simply "m-xylene."
  • It is a type of aromatic hydrocarbon compound with a chemical structure that consists of a benzene ring substituted with two methyl groups in the meta position, which means they are attached to carbon atoms in positions 1 and 3 on the benzene ring.

Additional Information

• BHC:-
  • It stands for "Benzene Hexachloride." It's a chemical compound that exists in multiple isomeric forms, including alpha-BHC, beta-BHC, gamma-BHC, and delta-BHC.
  • These isomers are also known by various other names, such as Lindane (gamma-BHC) and Kwell (a brand name for lindane). 
• Toluene:-
  • It is also known as methylbenzene, is a common aromatic hydrocarbon compound.
  • Its chemical formula is C7H8. Toluene is a clear, colorless liquid with a distinct sweet and pungent smell.
  • It is primarily used as a solvent in various industrial processes and as a precursor for the production of other chemicals.
