Question

How many $\beta$-carbon atoms does 2-Bromobutane have?

• A. 0
• B. 1
• C. 2
• D. 3

Answer 1

The correct option is B 1

A $\beta$ carbon is the carbon atom that is adjacent to the carbon atom that is attached to the halogen. In 2-Bromobutane, the halogen is at position C-2, so the $\alpha$ carbon has one carbon on either side, making it two $\beta$ carbons.
