Which of the following oxidation state assignments is/are correct?

AP in $H X_{3} PO X_{2}$ is $+ 1$
BAverage S in $S X_{4} O X_{6} X^{2 -}$ is $+ 2.5$
CN in $N X_{2} H X_{4}$ is $- 1$
DCl in $Cl X_{2} O X_{7}$ is $+ 7$

Answer: A, B, D

H X_{3} PO X_{2}

:

3 + x - 4 = 0

gives

+ 1

.

S X_{4} O X_{6} X^{2 -}

:

4 x - 12 = - 2

gives

+ 2.5

.

Cl X_{2} O X_{7}

:

2 x - 14 = 0

gives

+ 7

. In

N X_{2} H X_{4}

:

2 x + 4 = 0

gives

- 2

, not

- 1

.
