In which species does the underlined element (first-named, central element) have oxidation number $+ 3$ ? Species: (A) N in $HNO X_{2}$ , (B) Cl in $ClF X_{3}$ , (C) P in $H X_{3} PO X_{3}$ , (D) P in $H X_{3} PO X_{4}$ . Select all correct options.

AN in $HNO X_{2}$
BCl in $ClF X_{3}$
CP in $H X_{3} PO X_{3}$
DP in $H X_{3} PO X_{4}$

Answer: A, B, C

HNO X_{2}

:

1 + x - 4 = 0

gives

+ 3

.

ClF X_{3}

:

x - 3 = 0

gives

+ 3

.

H X_{3} PO X_{3}

:

3 + x - 6 = 0

gives

+ 3

.

H X_{3} PO X_{4}

:

3 + x - 8 = 0

gives

+ 5

.
