Compare aromatic & alicyclic compounds?
Answer:
Aromatic compounds have a closed (cyclic) planar system of delocalised pi-bonds consisting of 4n+2 (where n is a positive integer) electrons. The classic example is benzene which is often depicted as though it has a six-carbon ring with alternate double and single bonds between them. In fact the 'double' bonds form a delocalised system of pi-bonds extending over all six carbon atoms. Aromatic compounds have a much higher stability than compounds containing 'real' double bonds so they are resistant to addition reactions, generally undergoing substitution reactions in which the aromatic system is retained.
Alicyclic compounds are compounds in which there is one or more closed path of bonded atoms making up a ring which is not aromatic (see above). The bonds between the atoms may be any order (single, double, triple). Multiple bonds (i.e. double, triple) in alicyclic compounds will typically undergo addition reactions in which the bond is broken and other atoms or groups are added to the atoms at either end of the multiple bond.

==============================...
AROMATIC COMPUNDS
Aromatic compound, an organic chemical compound that contains aromatic rings (arenes) like benzene, pyridine, or indole.
These compounds exhibit an unusual stability known as aromaticity, which can be understood using Hückel's rule.
The term aromatic in chemistry is no longer associated with aroma, and many aromatic compounds have no smell.

ALICYCLIC COMPOUNDS
An alicyclic compound is an organic compound that is both aliphatic and cyclic.
They contain one or more all-carbon rings which may be either saturated or unsaturated, but do not have aromatic character.
Alicyclic compounds may or may not have aliphatic side chains attached.
Simple alicyclic compounds are the cycloalkanes cyclopropane, cyclobutane and cyclohexane.
Bicyclic alkanes are norbornene and norbornadiene. Spiro compounds have bicyclic connected through one carbon atom.
