Question

How many optical isomers are possible for a compound having four asymmetric carbon atoms?

• A. 16
• B. 8
• C. 12
• D. 4

Hint:

This formula applies when no meso form is present.

Answer 1

The Correct Option is A

Step 1: Recall formula for optical isomers.
Maximum number of optical isomers is given by: \[ 2^n \] where \(n\) is the number of asymmetric carbon atoms.
Step 2: Substitute given value.
\[ n = 4 \Rightarrow 2^4 = 16 \] Step 3: Conclusion.
Therefore, 16 optical isomers are possible.
