Question

Assertion (A): Aqueous Fe^2+ is paramagnetic with a spin-only magnetic moment of 4.90 BM. Reason (R): In [Fe(H2O)6]^2+, the 3d^6 electrons are all paired because water is a strong-field ligand.

Accepted Answer

A is true but R is false

Answer

Both A and R are true and R is the correct explanation of A

Answer

Both A and R are true but R is not the correct explanation of A

Answer

A is false but R is true

Assertion (A): Aqueous $Fe X^{2 +}$ is paramagnetic with a spin-only magnetic moment of 4.90 BM. Reason (R): In $[Fe (H X_{2} O) X_{6}] X^{2 +}$ , the $3 d^{6}$ electrons are all paired because water is a strong-field ligand.
