Options:
A) 3, 3, 3
B) 3, 2, -3
C) 2, 2, 2
D) 3, 2, 2
Show Answer
Answer:
Correct Answer: C
Solution:
The oxidation number can be obtained when we write their structures. In the coordinate bond, no charge transfer is considered if the donor is more electronegative than the acceptor atom. Bond breaking, as shown, indicates a +2 charge on carbon in all cases.
