The calculated magnetic moment value for the $Fe^{2+}$ ion in $BM$ is:

What are the number of possible geometric isomers,optical isomers,and total isomers for the complex $[CoCl_2(en)(NH_3)_2]^{+}$ respectively?

In the nitroprusside ion,the iron exists as $Fe^{2+}$ and $NO$ as $NO^{+}$ rather than $Fe^{3+}$ and $NO$ respectively. These forms of ions are established with the help of
