Which of the following are disproportionation reaction:

A

`F_2 +H_2 O to HOF +HF`

B

` 2HCHO +NaOh to HCOONa +CH_3 OH`

C

`P_(4(s)) + 3NaOH +3H_2 O to PH_3 + 3NaH_2 PO_2 `

D

`2NO_2 +2KOH to KNO_2 +KNO_3 +H_2 O`

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
`overset(0)(F_2 +H_2 overset(-2)(O) to overset(0-1)(HOF )+ overset(-1)(HF)`
(Since F is the most electronegative element, it can not exist in +1 oxidation state)
