Q. Illustrate Aromatics compounds?

Ans.

Benzene (C6H6) is the prototype of an important class of hydrocarbons called aromatic compounds. Benzene is a ring of 6 carbon atoms with bonds between the carbons which are somewhat like alternating double bonds. These double bonds resonate. This means they alternate back and forth between the carbons.

Benzene's structural formula can also be represented by a ring with a circle inside:

Substituting one of benzene's hydrogens with an alcohol functional group (i.e., with an -OH group) creates the compound phenol.
