Which of the following compounds can be classified as aryl halides?
1.  p-ClC6H4CH2CH(CH3)2
2.  p-CH3CHCl(C6H4)CH2CH3
3.  o-BrH2C-C6H4CH(CH3)CH2CH3
4.  C6H5-Cl


Write the structure of the given compounds.


On comparing the above structures it is very obvious that in compound (a) and compound (d),

the halogen atom is directly connected to aromatic ring hence these compounds are divided

as aryl halides.
