JEE Advanced levelOne or more correct optionsDifficulty 3 of 3bn162

Select ALL cases in which the specified atom has oxidation number (or average) of zero (H is $+ 1$ , Cl is $- 1$ , O is $- 2$ , CO neutral).

ANi in $Ni (CO) X_{4}$
BC in $CH X_{2} Cl X_{2}$
CN in $N X_{2} H X_{4}$
DC in $C X_{6} H X_{12} O X_{6}$ (average)

Answer: A, B, D

Ni (CO) X_{4}

:

0

.

CH X_{2} Cl X_{2}

:

x + 2 - 2 = 0

. Glucose:

6 x + 12 - 12 = 0

. In

N X_{2} H X_{4}

:

2 x + 4 = 0

, so

- 2

.
