If a compound has 3 chiral carbons What is the number of optically active isomers?
Correct answer: C. 8
- A. 3
- B. 4
- C. 8
- D. 9
Explanation
The maximum number of stereoisomers that a molecule can have is 2^n,where n is the number of chiral centres.A molecule with three chiral centres will have 2^3= 8 stereoisomers. Example: The aldopentoses all have three chiral carbons,and there are eight stereoisomism.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
