What is the of number of chiral carbon atoms present in 2-Bromo-3,4,5-trimethylhexane ?
Options
- A1
- B2
- C3
- D4
Correct answer
C. 3
Step-by-step solution
The structure of 2-Bromo-3,4,5-trimethylhexane is: CH₃ - CH(Br) - CH(CH₃) - CH(CH₃) - CH(CH₃) - CH₃ Let us examine each carbon atom in the principal chain for chirality (a chiral carbon must be attached to four different groups): C1: Attached to three identical hydrogen atoms Achiral. C2: Attached to -H , -Br , -CH₃ , and -CH(CH₃)CH(CH₃)CH(CH₃)₂ . All four groups are different Chiral. C3: Attached to -H , -CH₃ , -CH(Br)CH₃ , and -CH(CH₃)CH(CH₃)₂ . All four groups are different Chiral. C4: Attached to -H , -CH₃ , -C
