A) \[+{{10}^{o}}\]
B) \[+{{7}^{o}}\]
C) \[+{{14}^{o}}\]
D) \[-{{7}^{o}}\]
Correct Answer: B
Solution :
As there is 30% racemisation, the given mixture contains \[=\left( 70+\frac{30}{2} \right)%\] d-isomer and \[\left( \frac{30}{2} \right)%\] \[l-\]isomer. \[\therefore \] Specific rotation of mixture \[=\frac{85\times {{10}^{o}}}{100}+\frac{15(-{{10}^{o}})}{100}={{7}^{o}}\].You need to login to perform this action.
