Question

Magnetic moment (spin only) of octahedron
complex having CFSE-0.8A, and surrounded
by weak field ligands can be
1)root 15
(2)root 8
3) both (4) None of these​

Answer 1

Answer:

here's your answer

Explanation:

The octahedral complex with CFSE=−0.8Δ

o

surrounded by weak field ligands can have one or more unpaired electrons.

The spin only magnetic moment is given by the formula μ

eff

=

n(n+2)

B.M..

For two unpaired electrons, the expression becomes μ

eff

=

2(2+2)

B.M.=

8

B.M..

For three unpaired electrons, the expression becomes μ

eff

=

3(3+2)

B.M.=

15

B.M..

Thus, both options A and B are correct
