Answer:
[MA4B2]2+
Explanation:
Octahedral species are species that has a coordination number of of six. This means that six ligands are attached to the central metal atom/ion.
For any octahedral specie to exhibit geometrical or cis-trans isomerism, it must have the formula EX2Y4 as in [MA4B2]2+, hence the answer above.
Molecular Weight (MW) is the sum of the atomic weights/masses (AM) of every atom in a compound or molecule. Thus, we would add the AM of Mg + 2×[N+(O×3)]:
Mg = 24.31
N = 14.01
O = 16
So we have: Mg + 2×[N+(O×3)] = 24.31 + 2×[14.01+(16×3)] = 24.31+2×[14.01+48] = 24.31+ 2×62.01 = 24.31+124.02 = 148.33
C) is the correct answer
The correct answer is A, opposite spin of two electrons.
I hope this helped xoxoxo
