A. `H_(3)PO_(4) gt H_(4)P_(2)O_(6) gt H_(3)PO_(3) gt H_(3)PO_(2)`
B. `H_(3)PO_(3) gt H_(3)PO_(2) gt H_(3)PO_(4) gt H_(4)P_(2)O_(6)`
C. `H_(3)PO_(2) gt H_(3)PO_(3) gt H_(4)P_(2)O_(6) gtH_(3)PO_(4)`
D. `H_(3)PO_(4) gt H_(3)PO_(2) gt H_(3)PO_(3)gtH_(4)P_(2)O_(6)`

Answer 1

Correct Answer - A
`H_(3)PO_(4) "oxidation state of (P)=+5"`
`H_(3)P_(2)O_(6) "oxidation state of (P)=+4"`
`H_(3)PO_(2) "oxidation state of (P)=+1"`
`H_(3)PO_(2) "oxidation state of (P)=+1"`
`H_(3)PO_(2) gt H_(4)P_(2)O_(6) gt H_(3)PO_(3) gt H_(2)PO_(2)`
