Predict the number of stereoisomers in `CH_(2)OH.(CHOH)_(4).CHO`.

A

16

B

8

C

4

D

2

Text Solution

Verified by Experts

The correct Answer is:
A
Terminal groups are different. The number of asymmetric `C` atoms is four
`(HOCH_(2)overset(**)CH(OH)overset(**)CH(OH)overset(**)CH(OH)overset(**)CH(OH)CH_(2)OH)`
Therefore, the number of stereiosomers (optical isomers) is
`2^(n)=2^(4)=16`
(where `n` is the number of asymmetrical `C` atoms)
