(IIT JEE 1999)
a) have 4nπ electrons
b) have (4n+2)π electrons
c) be planar
d) be cyclic
Aromatic systems are planar cyclic systems with (4n+2)π electrons in conjugation and resist addition reactions.
Options 'b', 'c' and 'd' are correct.
(IIT JEE 1983)
Benzene is an aromatic compound and is stabilized due to resonance or delocalization of π electrons. When it undergoes addition reactions, it will lose resonance stabilization. Hence it resists electrophilic additions to double bonds in it.
Rather, it prefers to undergo electrophilic substitution reactions.
1) What is an electrophile?
2) What is addition reaction?
3) What is substitution reaction?
4) What is the structure of benzene?
