Optical activity - 3 | Stereoisomers
Organic Chemistry 1 - Optical activity - 3
Molecule A has an D = - 88°.
Draw the structure of B, which has an D = + 88°.
Calculate the D of a 70/30 mixture of A and B.
Draw the structure of C, which is a constitutional isomer of A and has an D = 0°.
Other answers are also possible for C.
D of a 70/30 mixture of A and B: (-88) x (0.7) + (+88) x (0.3) = -35.2°.
