alleryNumber of stereoisomers of 2-bromobutane:
A8
B4
C2 (one chiral center → R and S enantiomers)
D1
Answer & Solution
Correct answer: C. 2 (one chiral center → R and S enantiomers)
2-bromobutane: CH₃-CHBr-CH₂-CH₃.
C2 is chiral (bonded to CH₃, Br, H, C₂H₅).
1 chiral center → 2^1 = 2 enantiomers (R, S).
