The number of chiral carbons in `beta-D (+)-`glucose is:

Options

A. Five
B. Six
C. Three
D. Four

Answer

A

Explanation

In the open structure of `D-(+)-` glucose, these are 4 chiral carbon atoms. During the hemiacetal formation, `C - 1` of `D-(+)-` glucose also becomes chiral, resulting in a total of 5 chiral carbon atoms in `beta-D-(+)-` glucose
