The necessary and sufficient conditions for a compound to be aromatic are:
(i) It should be cyclic with alternate single and double bonds and the cyclic -electron cloud should surround all the carbon atoms at the ring.
(ii) It should be planar.
(iii) It should contain (4n + 2) -electrons where, n = 0, 1, 2, 3,.... etc.

One mole of a solute A is dissolved in a given volume of a solvent. The association of the solute takes place according to nA [A]n. The van't Hoff factor (i) is expressed as:
i = 1 - x
i = 1 +
i =
i = 1
