A coordination complex compound of cobalt has the molecular formula containing five ammonia molecules, one nitro group and two chlorine atoms for one cobalt atom. One mole of this compound produces three mole ions in an aqueous solution. On reacting with an excess of ${\mathrm{AgNO}}_3,$ two moles of $\mathrm{AgCl}$ is precipitated. The ionic formula for this complex would be

The molecular formula of diphenyl methane  is ${\mathrm{C}}_{13}{\mathrm{H}}_{12}$.

How many structural isomers are possible when one of the hydrogens is replaced by a chlorine atom?

Which one of the following has an optical isomer? (en-enthylenediamine)

Choose the complex, which is paramagnetic

(i) ${\left[\mathrm{Fe}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{2+}$

(ii) ${\mathrm{K}}_3\left[\mathrm{Cr}{\left(\mathrm{CN}\right)}_6\right]$

(iii) ${\mathrm{K}}_3\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]$

(iv) ${\mathrm{K}}_2\left[\mathrm{Ni}{\left(\mathrm{CN}\right)}_4\right]$

The complex showing a spin-only magnetic moment of $2.82\text{B}.\text{M}.$ is:

Copper sulphate solution reacts with $\mathrm{KCN}$ to give

In the silver plating of copper, $\mathrm{K}\left[\mathrm{Ag}{\left(\mathrm{CN}\right)}_2\right]$ is used instead of ${\mathrm{AgNO}}_3$. The reason is
