WebAre enantiomers optically active compounds? Yes, it is true that all enantiomers are known to be optically active. Optical activity is one of the core properties of enantiomers. This is because enantiomers are isomers … WebJan 13, 2024 · Specific rotation is characteristic value for every optically active compound. Observed rotation of a compound may vary as per variation in concentration and length of the sample tube, but the specific rotation is a constant value for every optically active compound. Following is a formula used for calculation of specific rotation:
