The optically active tartaric acid is named as D-(+)-tartaric acid because it has a positive

Options

A. Optical rotation and is 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

Answer

C

Explanation

D-word is used to represent the arrangement of -OH group in right side at second last carbon atoms as in glyceraldehyde.
`{:(" "CHO),(" |"),(H-C-OH),(" |"),(" "CH_(2)OH):}`
and (+) sign is used to represent the rotation in right side. Hence, in D-(+)-tartaric acid.

Hence, it has a positive optical rotation and it is devided with glyceraldehyde.
