Which of the following are correct for the complex ${\left[Fe{\left(H_{2}O\right)}_5\left(NO\right)\right]}^{+2}$ ion

${\left[F{e}^{+1}{\left(H_{2}O\right)}_5{N}^{+}O\right]}^{+2}\Rightarrow Fe$is +1

Since  $N^{+}O$ is a strong ligand and $H_{2}O$  is weak, only one passing of 3d and 4s electrons occurs.

  $n=3\Rightarrow$ Magnetic moment = 3.89 BM
  $\Rightarrow s{p}^3{d}^2$ Hybridisation
  $\Rightarrow$ Outer Octahedral
