Question

Draw the aromatic compound toluene (methylbenzene). show all hydrogen atoms, including those on the ring.

Answer 1

Aromatic compound has continuous cyclic structure with( 4n+2)π electrons (Huckels rule), where n = 0,1,2…

Here number of pi electron are 6, where 4 from two double bond and 2 from nitrogen non-bonding electrons, hence it has total 6 pi electrons, therefore

6= ( 4n+2)π

4 = 4n

n =1

Hence it is an aromatic compound
