A white 'A' on heating decomposes to produce two products 'B' and 'C'. 'B' on reaction with white phosphorous produces 'D', which is a strong dehydrating agent. 'D' on reaction with perchloric acid converts it to its anhydride.
The product obtained on hydrolysis (complete) of D is:

A

mixture of `H_(3)PO_(3)` and `H_(3)PO_(4)`

B

only `PH_(3)`

C

only `H_(3)PO_(4)`

D

mixture of `H_(3)PO_(3)` and `H_(3)PO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`NH_(4)NO_(3) overset(Delta)(rarr)N_(2)O+H_(2)O`
`N_(2)O+P_(4)rarrP_(4)O_(10)+N_(2)`
`HClO_(4)+P_(4)O_(10)rarrCl_(2)O_(7)+HPO_(3)`
`A=NH_(4)NO_(3),C=H_(2)O,D=P_(4)O_(10)`
`P_(4)O_(10)+6H_(2)Orarr4H_(3)PO_(4)`.
