What are \(X, Y\) and \(Z\) in the following reaction?
- A \(R-\mathrm{Cl} \quad \mathrm{HCl} \quad \mathrm{POCl}_3\)
- B \(\begin{array}{lll}R O R & \mathrm{H}_3 \mathrm{PO}_3 & \mathrm{H}_2 \mathrm{O}\end{array}\)
- C \(\mathrm{R}-\mathrm{Cl} \quad \mathrm{H}_2 \mathrm{O} \quad \mathrm{POCl}_3\)
- D ROR \(\quad \mathrm{H}_2 \mathrm{O} \quad \mathrm{POCl}_3\)
Answer & Solution
Correct Answer
(A) \(R-\mathrm{Cl} \quad \mathrm{HCl} \quad \mathrm{POCl}_3\)
Step-by-step Solution
Detailed explanation
The reaction of alcohol \((R-\mathrm{OH})\) with \(\mathrm{PCl}_5\), the reaction is leading to formation of \(R-\mathrm{Cl}, \mathrm{HCl}\) and \(\mathrm{POCl}_3\). \[ R-\mathrm{OH}+\mathrm{PCl}_5 \longrightarrow R-\mathrm{Cl}+\mathrm{HCl}+\mathrm{POCl}_3 \]
