Options
- A(A)-(IV), (B)-(I), (C)-(II), (D)-(III)
- B(A)-(I), (B)-(IV), (C)-(II), (D)-(III)
- C(A)-(IV), (B)-(II), (C)-(I), (D)-(III)
- D(A)-(IV), (B)-(I), (C)-(III), (D)-(II)
Correct answer
A. (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
Step-by-step solution
(A) CH₃-CH(Br)-CH₂-CH(Cl)-CH(Cl)-CH₃ : Numbering from right to left gives locants 2, 3, 5. Numbering from left to right gives 2, 4, 5. The lowest locant set is 2, 3, 5. Substituents are listed alphabetically. The name is 5-bromo-2,3-dichlorohexane. Matches with (IV). (B) CH₃-CH₂-CH₂-CH(CH₂OH)-CH₂-CH₃ : The principal functional group is -OH. The parent chain must include the carbon attached to the -OH group, even if it is not the longest continuous chain in the molecule. The longest chain containing the -OH group ha
