Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

4 isomers are not possible
Both the structures (c) and (d) have same structure and and one can be obtain by rotation of 180° .So only 3 isomers are possible not 4.

1,2-diaminopropane (pn) is an unsymmetrical bidentate ligand. The complex [Co(en)(pn)(NO2)2]+ can form two cis and two trans isomers. Both the cis forms give two optical. while trans isomer is optically inactive..so total isomers are 5 not 4. isomers as shown below.
Sir i am asking for only geometrical isomers not total isomers.
but I've explained everything
yes sir..Thank u..☺
you welcome
sir. Those 2 trans isomers are equivalent and can be obtained by rotation of 180°.So how those trans isomers are different from each other
it gives only one trans and two cis isomers.. trans isomer is optically inactive due to molecular plane while both of two cis isomers are optically active so the total isomers (OI + GI) are 5
yes. Sir. there is a mistake in the material. It says 2 cis and 2 trans
