1.	The specific rotation of a pure enantiomer is `+16^(@)` its observed rotation if it is isolated from a reaction with 25% racemisation and 75% retention is,A. `-12^(@)`B. `+12^(@)`C. `+16^(@)`D. `-16^(@)`
Answer» Correct Answer - B % enantiomeric excess `=("observed specific rotation")/("Specific ration of pure enantiomer")xx100` observed specific rotation`=(3//4)/(100)xx(+16^(@))xx100=+12^(@)`
