QJEEM22Chb9f0: JEE Main 2022 Chemistry - Class 11 JEEM22Chb9f0 Solution: Optical activity of an enantiomeric mixture is and the specific …

Optical activity of an enantiomeric mixture is +12.6∘+12.6^{\circ} and the specific rotation of (+)(+) isomer is +30∘+30^{\circ} . The optical purity is __________ %\% .

Step-by-Step Verified Solution

Optical purity = Total rotation  Specific rotation ×100=\frac{\text { Total rotation }}{\text { Specific rotation }} \times 100

amp;=12⋅630×100amp;=42%\begin{aligned}&=\frac{12 \cdot 6}{30} \times 100 \\\\&=42 \%\end{aligned}
