JEE Advanced levelOne or more correct optionsDifficulty 3 of 3bn051

Select the species in which the named central atom has oxidation number $+ 4$ (O is $- 2$ , F is $- 1$ ).

ASi in $[SiF X_{6}] X^{2 -}$
BCl in $ClO X_{2}$
CN in $NO X_{2} X^{-}$
DS in $SO X_{3} X^{2 -}$

Answer: A, B, D

SO X_{3} X^{2 -}

:

x - 6 = - 2

gives S

+ 4

.

ClO X_{2}

:

x - 4 = 0

gives Cl

+ 4

.

[SiF X_{6}] X^{2 -}

:

x - 6 = - 2

gives Si

+ 4

.

NO X_{2} X^{-}

:

x - 4 = - 1

gives N

+ 3

.
