Question

Which xylene gives only one monobromo derivative?

Answer 1

Xylene

• Xylene is an organic chemical compound.
• It is also known as dimethyl benzene or Xylol.
• It consists of a central benzene ring attached with two methyl groups as substituents.
• The structure of xylene is as follows:-
• 

Reaction of xylene with ${\mathrm{Br}}_2$

• In ortho, para, and meta-xylene, the methyl group is present.
• The Methyl group is an ortho-para directing group.
• So, an attack of bromine is possible only in ortho and para positions.
• The reaction is as follows:-
• 
• So, para-xylene gives only one monobromo derivative.
