NEET 2026 Chemistry Alcohols and Haloalkanes MCQ Question
Type: MCQ-conceptual-Medium-Class 11
In the following reaction sequence, X and Z respectively are: CH₃CH₂CH₂ − OH + PCl₅ ⟶ CH₃CH₂CH₂Cl + X + HCl
A
X = POCl₃; Z = CH₃ − CH − CH₃ Br
B
X = POCl₃; Z = CH₃CH₂CH₂ − Br
C
X = H₃PO₃; Z = CH₃ − CH − CH₃ Br
D
X = H₃PO₃; Z = CH₃CH₂CH₂ − Br
Correct Answer
Option B
Detailed Explanation
In the reaction sequence, the alcohol reacts with PCl₅ to form the corresponding alkyl chloride and POCl₃. The subsequent reaction with HBr converts the alkyl chloride to the alkyl bromide.
