Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Stereochemistry is the study of how molecules are affected by the way their atoms are arranged in space. ... Stereoisomers have the same atoms, they are joined the same way, but the atoms are arranged differently in space.

There are three types of selectivity in organic chemistry -1.Regioselectivity 2.Chemoselectivity 3.Stereoselectivity Regioselectivity :-When a reaction that can potentially yield two or more constitutional isomers actually produces only one (or a predominance of one ),the reaction is said to be regioselective. Chemists describe reactions like the -Markovnikov additions of hydrogen halides to alkenes as being regioselective.The addition of HX to an unsymmetrical alkene such as propene could conceivably yield two constitutional isomers ,as we have seen ,however,the reaction yields only one ,and therefore it is regioselective. Stereoselective reactions :-When a reaction that lead to a preferential formation of one stereoisomer over other stereoisomers that could possibly be formed.If a reaction produces preferentially one enantiomer over its mirror image ,the reaction is said to be enantioselective .If a reaction leads preferentially to one diastereomer over others that are possible ,the reaction is said to be diastereoselective. Chemoselective :- when a substrate having two or more distinct functional group ,reacts with only one functional group at a time ,is known as chemoselective,basically it said that which functional group will react .
