    The catalyst which shows preference or selectivity towards a reactant or substrate because of its shape or size is called a shape selective catalyst. These catalytic reactions depend on the pore structure of the catalyst and the size or shape of the substrates and products. e.g. Zeolites.

    It is based on the principle of separation or purification by chromatography Al2O3 is used as adsorbent. The mixture to be separated is taken in suitable solvent and applied on the coloumn.They are eluted out using suitable solvent. The weakly absorbed component is eluted first ,then the more strongly adsorbed on. This method is suitable for those elements which are available only in minute quantity and these impurities are not very much different in their chemical behaviour from the element to be purified

    Those stereoisomers which are differing in its configuration at only one chiral carbon atom are called as Epimers. e.g, glucose and galactose are Epimers of each other, as they differ in only in the position of hydroxyl group at C4(chiral carbon atom).

    Butanol is more soluble than butan1 amine as butanol have OH and also water is of H+and OH- in short can say OH groups arevery much similar to water molecules. This is also due polarity as they are more polar than N H bonds so that the intermolecular force will be stronger..
