Identify and indicate the presence of centre of chirality, if any, in the following molecules. How many stereoisomers are possible for those containing chiral centre ? (i) 1, 2 dichloropropane (ii) 3-bromo -pent -1-ene

Answer»

Solution :(i) `underset("as given below: ") (ClCH_(2) - underset(Cl) underset(|)overset(***)CH - CH_(3)) `has one CENTRE of CHIRALITY denoted by`***` MARK . It has two stereoisomers as given below : <BR>
(II) `underset("stereoisomers as shown below:") (CH_(3) - CH_(2) - underset(Br) underset(|) overset(***) CH - CH = CH_(2)) `has one centre of chirality denoted by `***` mark and has two
