Answer 1

Answer:

(A) BO

3

3−

, CO

3

2−

, NO

3

−

contains 32 electrons each. Hence, they are isoelectronic.

(B) SO

3

2−

, contains 34 electrons. CO

3

2−

contains 32 electrons and NO

3

−

THIS IS THE ANSWER

contains 32 electrons. Thus, these species are not isoelectronic.

(C) CN

−

, N

2

, C

2

2−

contains 14 electrons each. Hence, they are isoelectronic.

(D) PO

4

3−

, SO

4

2−

, ClO
