1.	A pair of stereoisomers might be classified in various ways. Which of the followign statement are true with respect to pairs of stereoisomers ? (a) They might be configurational isomers (b) They might be diastereomers (c ) They might be configurational isomers (d) They might be tautomers (e) They might be conformationasl isomer they might be enantiomers (g) they might be positionatal isomers
Answer» a,B,c,e b,d,e,f,g a,b,f a,b,c,f Solution :STEREOISOMERS are actually configurational ISOMERS. Thus they might be DIASTEREOMERS (geometrical/optical) and enantiomers (mirror image non-super imposeable). Stereoisomers are not CONSTITUTIONAL isomers, thus, can't be tautomers, positional. Since, conformational isomers deals with bond rotation without change in confituration, thus, stereoisomers can't be conformational isomers.
