A) optical rotation and derived from D-glucose
B) pH in organic solvent
C) optical rotation and is derived from\[D-(+)-\]glyceraldehyde
D) optical rotation when substituted by deuterium
Correct Answer: A
Solution :
The prefix D-indicates series, ie, the compound is derived from D-series, while the sign\[(+)-\] indicates the nature of optical rotation. The sign of rotation may change during reaction eg, \[D-(+)-\]glyceraldehyde gives\[D-(-)-\]tartaric acid. Thus,\[D-(+)-\]tartaric acid belongs to D-series and has\[(+)-\]optical rotation.
