The device that is used for measuring the effect of opticallyactive compounds on plane-polarized light is called a18. If a sample is said to contain a 98.0% enantiomeric excessof the compound (+)-camphor, what would be the observedspecific rotation if the pure (+)-camphor was found to havea rotation of 44.1?19. An equimolar mixture of two enantiomers is called a20. X and Y are enantiomers with chemical formula C,H10: Aracemic mixture of X and Y treated with excess H, andPd/C was converted to a single compound Z (C,H1,) whichdid not show optical activity.
