Chloropicrin is obtained by the reaction

Considering $\mathrm{H}_2 \mathrm{O}$ as a weak field ligand, the number of unpaired electrons in $\left[\mathrm{Mn}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+}$ will be: (atomic number of $\mathrm{Mn}=25$ )

In a regular octahedral molecule, $\mathrm{MX}_6$ the number of $\mathrm{X}-\mathrm{M}-\mathrm{X}$ bonds at $180^{\circ}$ is:

In an octahedral structure, the pair of $d$ orbitals involved in $d^2 s p^2$ hybridisation is:

In $\mathrm{BrF}_3$ molecule, the lone pairs occupy equatorial positions to minimize:

Ionic radii are:

$\mathrm{H}_2 \mathrm{O}$ is dipolar whereas $\mathrm{BeF}_2$ is not. It is because:

$\mathrm{CN}^{-}$is strong field ligand. This is due to the fact that :

Lanthanoids are:
