Question

All chiral D-sugars rotate plane-polarized light :
Options
A clockwise
B counterclockwise
C +20.0°
D in a direction that cannot be predicted but must be determined experimentally
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

The D/L configuration of a sugar does not predict the direction of optical rotation. D-sugars can be dextrorotatory (+) or levorotatory (-). The direction must be determined experimentally.

Hint

Does D configuration predict direction of rotation?
