The correct structure of ${\mathrm{Co}}_2{\left(\mathrm{CO}\right)}_8$

Which of the following properties is/are common amongst the oxy acids ${\mathrm{H}}_2{ \mathrm{S}}_2{\mathrm{O}}_7,{\mathrm{H}}_4{\mathrm{P}}_2{\mathrm{O}}_5$ and ${\mathrm{H}}_3{\mathrm{P}}_3{\mathrm{O}}_9$

Consider the complex ion${\left[{\mathrm{NiA}}_4{ \mathrm{B}}_2\right]}^{2+}$ which exist in both $\mathrm{C}$ is and trans isomers. $\mathrm{C}$ is isomer is paramagnetic while trans isomer is diamagnetic. From this it can be concluded that

In which of the following compounds there is no change in magnetic moment. When all the ligands are replaced by ${\mathrm{CN}}^{-}$ ions to from cyano complexes/complex ions

Correct statement for complex ions ${\left[\mathrm{Mn}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{2+}$ and ${\left[{\mathrm{MnBr}}_4\right]}^{2-}$ is

Select the CORRECT statement(s):

The complex $\left[\mathrm{Co}{\left(\mathrm{en}\right)}_2{ \mathrm{F}}_2\right]$ can exist in two geometrical isomers Cis and trans. Regarding these isomers the correct statements are

The crystal field stabilization energy ($CFSE$) in ${\mathrm{cm}}^{-1}$ for ${\left[\mathrm{Ti}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}$ that has absorption maximum at $500 \mathrm{nm}$ is $x\times {10}^2{ \mathrm{cm}}^{-1}$. Then $x$ is
