1.	The specific rotation of a pure enantiomers is `+12^(@)`. What will be its observed rotation if it is isolated form a reaction with `20%` racemization and `80%` retention.A. `+9.6^(@)`B. `-9.6^(@)`C. `+2.4^(@)`D. `-2.4^(@)`
Answer» Correct Answer - A `%`optical purity `= (alpha_(obs))/([alpha]_(D)) xx 100%` Thus, `alpha_(obs) = (80)/(100) (+12^(@))` `= +9.6^(@)`
