Optical Acitivity of GHB

ORGO1-S1ZXGH

If somebody wants to sell a detector for GHB to an organic chemist by claiming that it can find out the concentration of GHB in drinks by measuring the optical rotation of the drinks, which of the following statements would be the MOST likely response from that organic chemist?

A

The organic chemist would buy the detector. He or she would point out that GHB is chiral, and its optical rotation is directly proportional to its concentration.

B

The organic chemist would not buy the detector. He or she would point out that GHB is racemic, and its optical rotation is always zero at all concentrations.

C

The organic chemist would not buy the detector. He or she would point out that GHB is not chiral, and its optical rotation is always zero at all concentrations.

D

The organic chemist would buy the detector. He or she would point out that GHB is achiral, and its optical rotation is directly proportional to its concentration.
