Which of the following statements correctly pertains to a pair of enantiomers?

Question

a. They rotate the plane of polarized light by differing amounts and in opposite directions.

b. They rotate the plane of polarized light by differing amounts and in the same direction.

c. They have the same melting point, but they have different boiling points.

d. The have different melting points.

e. They rotate the plane of polarized light by exactly the same amount and in opposite directions.

Answer 1

e and just e.  boiling point, melting point, molecular structure, etc are all the same..

only times it makes a difference is in a stereospecific reaction

Answer 2

(e) is the correct answer.

enantiomers are the non-superimposable mirror images of an optically active molecule and differ ONLY in the direction in which they rotate the plane of plane-polarised light.
