Question

Compounds A and B are two conformers of the same molecule. . E. Compounds A and B are not isomers. 33. Which of the following statements is true about compounds A and B drawn below? Br Br A. B. A. Compounds A and B cannot be separated by fractional distillation using an efficient fractionating column. B. Compounds A and B rotate the direction of plane-polarized light to an equal amount but in opposite directions C. A mixture of compounds A and B will show optical activity. D. Compounds A and B are both chiral compounds. E. Compounds A and B are enantiomers. Houare compounds A and B related?

Explanation / Answer

Answer:

Answer is option B. Because B and A is only having a difference in spacial arrangement of one group of atoms. So they are called as diasteromers.

A)The compounds can be separated by fractional distillation so that option is false. Only enantiomers cannot be detected by fractional distillation.

C) A mixture of these diastereomers will give a racemic mixture which do not show optical activity.Hence this option is also false.

D)Chiral compound is one which cannot be super imposable so compound A is chiral and compound B is not chiral.Hence statement is wrong.

E) Enantiomers are each of a pair of molecules that are mirror images of each other. So here it is not true.
