Answer 2

Hey buddy,
I think you misspelled the question.

● Correct question would be -
Why does PCl3 fumes in moist air?

● Answer -
- In presence of moist air, PCl3 undergoes hydrolysis to produce hydrochloric acid and phosphoric acid.
- Reaction involved in the process is -
PCl3 + 3H2O ---> H3PO3 + 3HCl
- HCl procuced here is in gaseous form and produces fumes in air.

Hope this helps...
