Question



What is the complete IUPAC name for Compound B?

In what way, if any, do the physical properties (melting point, boiling point, solubility, etc.) of Compounds B and C differ?

Can you predict the sign of optical rotation for Compound B, if it were isolated? If so, predict the sign and explain how you made the prediction; if not, explain why you cannot.

Can you predict the sign of optical rotation of the mixture of Compounds B and C formed in the given reaction? If so, predict the sign and explain how you made the prediction; if not, explain why you cannot.

Explanation / Answer

compounds B, C are enantiomers , so they differ mainly in rotation of optical rotation of plane polarised light.

Optical rotation sign or magnitude can be found out experimentally. Theoretically there is no way to find out such things.

when B and C are formed in equal quantities optical rotation of the mixture will be zero, since both B and C are enantiomers and both rotate plane polarised light with same magnitude but opposite directions , hence net rotation is zero. Apart from this optical rotation of individual component sign and magnitude is not posiible to get theoretically
