Isomerism — Medium JEE chemistry MCQ
The number of chiral centers in 2-bromo-3-chlorobutane is:
- A. 0
- B. 1
- C. 2
- D. 3
Solution
The structure is CH₃-CHBr-CHCl-CH₃. Both C-2 (attached to H, Br, CH₃, CHClCH₃) and C-3 (attached to H, Cl, CH₃, CHBrCH₃) are chiral centers since all four groups attached to them are different.
