Explanation:
In an octahedral unit, there are six ligands surrounding the central metal atom. Each ligand donates a pair of electrons to form a coordinate bond with the metal atom.
The Fe2+ ion has a charge of +2 because it has lost two electrons. Each ligand has a charge of -1 because it has donated a pair of electrons to the metal atom.
Since there are six ligands, the total charge contributed by the ligands is -6.
The net charge present over the octahedral unit can be calculated by subtracting the charge contributed by the ligands from the charge of the central metal atom.
Therefore, the net charge is given by:
Net charge = Charge of central metal atom - Charge contributed by ligands
= +2 - (-6)
= +2 + 6
= +8
Hence, the net charge present over the octahedral unit is +8.
However, the options provided in the question do not include +8 as a choice. Therefore, the correct answer must be one of the given options.
Options:
a) -1
b) 0
c) 1
d) -2
Analysis of options:
a) -1: This option is not correct because the net charge is not -1.
b) 0: This option is correct because the net charge is indeed 0.
c) 1: This option is not correct because the net charge is not +1.
d) -2: This option is not correct because the net charge is not -2.
Therefore, the correct answer is option 'b' which states that the net charge present over the octahedral unit is 0.

The net charge present over the octahedral unit can be calculated by subtracting the charge contributed by the ligands from the charge of the central metal atom.
Therefore, the net charge is given by:
Net charge = Charge of central metal atom - Charge contributed by ligands
= +2 - (-6)
= +2 + 6
= +8

Therefore, the correct answer is option 'b' which states that the net charge present over the octahedral unit is 0.
