Question

Which of the following is the byproduct when $R-OH$ is reacted with $PC{l}_3$?

• A. $POC{l}_3$
• B. $H_{3}P{O}_3$
• C. $HCl$
• D. None of these

Answer 1

Answer: (B)

$H_{3}P{O}_3$

$H_{3}P{O}_3$ is the byproduct when R-Cl is reacted with $PC{l}_3$

$3R-OH+PC{l}_3\to R-Cl+H_{3}P{O}_3$

In the final product, we get a byproduct of $H_{3}P{O}_3$

Hence option B is correct.
