What is the number of chiral carbon atoms present in 3,4-Dibromohexane?

Step-by-step solution

3,4-Dibromohexane has the molecular structure CH₃-CH₂-CHBr-CHBr-CH₂-CH₃ . A chiral carbon center requires four distinct substituents. Carbon atoms 1, 2, 5, and 6 are attached to multiple identical hydrogen atoms and cannot be chiral. Carbon 3 is bonded to H , Br , CH₂ CH₃ , and CHBrCH₂ CH₃ . Carbon 4 is bonded to H , Br , CH₃ CH₂ , and CHBrCH₃ . Both carbons 3 and 4 have four distinct substituents and are therefore chiral centers. 2
