Question

How many chiral isomers can be drawn from 2-bromo, 3-chloro butane

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is C

4

2-bromo, 3-chloro-butane has 2 chiral carbon atoms, hence has $2^2$=4 optical isomers

$C{H}_3-\underset{H}{\underset{|}{\stackrel{Br}{\stackrel{|}{C}}}}-\underset{H}{\underset{|}{\stackrel{Cl}{\stackrel{|}{C}}}}-C{H}_3$
