On reaction with Cl(2) phosphorous form...

On reaction with `Cl_(2)` phosphorous forms two types of halides 'A' and 'B'. Halide A is yellowish - white powder but halide 'B' is colourless only liquid. Identify A and B and wirte the formulas fo their hydrolysis products.

Text Solution

Verified by Experts

A is `PCl_(5)` (yellowish - white powder ) and B is `PCl_(3)` (colourless oily liquids).
`P_(4) + 10Cl_(2) to 4PCl_(5) , P_(4) + 6Cl_(2) to 4 PCl_(3)` .
Hydrolysis products are formed as follows:
`PCl_(3) + 3H_(2) O to H_(3)PO_(3) + 3HCl`
`PCL_(5) + 4H_(2)O to H_(3)PO_(4) + 5HCl`
