Question

A translucent white waxy solid (A) reacts with excess of chlorine to give a yellowish white powder (B). (B) reacts with organic compounds containing -OH group converting them into chloro derivatives. (B) on hydrolysis gives (C) and is finally converted to phosphoric acid. (A), (B) and (C) are?

• A. $P_4$,$PC{l}_3$,$H_{3}P{O}_4$
• B. $P_4$,$PC{l}_5$,$H_{3}P{O}_3$
• C. $P_4$,$PC{l}_5$,$POC{l}_3$
• D. $P_4$,$PC{l}_3$,$POC{l}_3$

Answer 1

The correct option is C $P_4$,$PC{l}_5$,$POC{l}_3$

A translucent white waxy solid (A) reacts with excess of chlorine to give a yellowish white powder (B). Here B is $PC{l}_5$.$PC{l}_5$ reacts with organic compounds containing -OH group converting them into chloro derivative $POC{l}_3.$.$PC{l}_5$ on hydrolysis gives (C).C is $POC{l}_3$ and is finally $POC{l}_3$ converted to phosphoric acid.

So (A), (B) and (C) are $P_4$,$PC{l}_5$,$POC{l}_3$.

Hence option C is correct.
