The resonance effect is defined as 'the polarity produced in the molecule by the interaction of two π-bonds or between a π -bond and lone pair of electrons present on an adjacent atom'. The effect is transmitted through the chain. There are two types of resonance or mesomeric effect designated as R or M effect.

When an organic compound is present in anaqueous medium, it is separated by shaking it with an organic solvent in which it is more soluble than in water. The organic solvent and the aqueous solution should be immiscible with each other so that they form two distinct layers which can be separated by separatory funnel. The organic solvent is later removed by distillation or by evaporation to get backthe compound. Differential extraction is carried out in a separatory funnel.
If the organic compound is less soluble in the organic solvent, a very large quantity of solvent would be required to extract even a very small quantity of the compou

(d) Electromeric effect is a temporary effect. The organic compounds having a multiple bond (a doubleor triple bond) show this effect in the presence of an attacking reagent only. It is defined as the complete transfer of a shared pair of? -electrons to one of the atoms joined by multiple bond on the demand of an attacking reagent.

(b) The difference in energy between the actual structure and the lowest energy resonance structure is called the resonance stabilisation energy or simply the resonance energy. The more the number of important contributing structures, the more is the resonance energy.
