If optical rotation produced by the compound \((A)\) is \(+52^{\circ}\), the one produced by compound (B) is :

If optical rotation produced by the compound \((A)\) is \(+52^{\circ}\), the one produced by compound (B) is :
  1. $-52^{\circ}$
  2. $+52^{\circ}$
  3. $0^{\circ}$
  4. Unpredictable

Solution

Since (A) and (B) are enantiomers, so specific rotation of \(\mathrm{B}\) is \(-52^{\circ}\) (because enantiomers have equal and opposite specific rotation Practice more ORGANIC CHEMISTRY – SOME BASIC PRINCIPLES AND TECHNIQUES questions on Aicharya
