Assertion : N atom has two different oxidation states in `NH_4NO_2`.
Reason : One N atom has-ve oxidation number, as it is attached with less electronegative H atom andother has +ve oxidation number as it is attached with more electronegative atom.

Options

A. If both (A) and (R) are correct and (R) is the correct explanation of (A).
B. If both (A) and (R) are correct, but (R) is not the correct explanation of (A).
C. If (A) is correct, but (R) is incorrect.
D. If both (A) and (R) are incorrect.

Answer

A

Explanation

N in `NH_4^(+)` is in -3 oxidation state and in `NO_2^(-)` it is in +3 oxidation state.
