CHECK THE SOLUTION.
(a,b,d)
[Co(en)(NH 3 ) 3 (H 2 O)] 3+ has 2 geometrical isomers
Compound [Co(CN) 2 (NH 3 ) 3 (H 2 O)] + will have three geometrical isomers.
[Co(en)(NH 3 ) 3 (H 2 O)] 3+ is diamagnetic
[Co(en)(NH 3 ) 3 (H 2 O)] 3+ absorbs light at longer wavelength as compared to [Co(en)(NH 3 ) 4 ] 3+ as H 2 O is weaker ligand than NH 3 .
