Benzene is a monocyclic compound. It is aromatic because it contains :

A)  6 carbons and 6 hydrogens

B)  3\[\pi -\]bonds

C)  \[6p-\] orbitals

D)  \[(4n+2)\pi \]electrons

Correct Answer: D

Solution :

                 According to Huckel rule compounds having \[(4n+2)\] \[\pi -\]electrons are aromatic compounds. Benzene is aromatic because it contains \[(4n+2)\]\[\pi -\] electrons. \[6\pi -\]electrons  if \[n=1\]then \[(4n+2)\pi =(4\times 1+2)\pi \]\[=6\pi -\]electrons So, benzene is aromatic in nature.
