- D1
Correct answer
B. 3
Step-by-step solution
Identifying chiral carbon atoms in 2-chloro-3,4,5-trimethylhexane The compound has structure: CH₃-CH(Cl)-CH(CH₃)-CH(CH₃)-CH(CH₃)-CH₃ Chiral centers require carbon bonded to four distinct groups. Terminal methyl carbons (C1 and C6) have three identical hydrogens and are not chiral. Carbons C2, C3, C4, and C5 each have four different substituents: C2: H, Cl, CH₃, and -CH(CH₃)CH(CH₃)CH(CH₃)CH₃ C3: H, CH₃, -CH(Cl)CH₃ , and -CH(CH₃)CH(CH₃)CH₃ C4: H, CH₃, -CH(CH₃)CH(Cl)CH₃ , and -CH(CH₃)CH₃ C5: H, CH₃ , -CH(CH₃)CH(CH₃)CH
