The specific rotation of a pure enantiomer is

+ 16^\circ .

Its observed rotation if it is isolated from a reaction with 25% recemisation and 75% retention is

View answer and explanation

Correct option: B

+ 12^\circ

Option B (

+ 12^\circ

) is correct because the observed rotation is proportional to the enantiomeric excess, which is reduced due to racemization.
