Find the sum of number of geometrical isomers for following complexes.

[CoCl 2 Br 2 ] 2–

[Rh(en) 3 ] 3+

[Cr(en) 2 Br 2 ] +

[Pt en Cl 2 ] (e) [Co(NH 3 ) 3 (NO 2 ) 3 ]

Text Solution

Verified by Experts

The correct answer is:

4 (0 + 0 + 2 + 0 + 2 = 4)

Sol. For CoCl 2 Br 2 → No. of G.I. = 0

For [Rh(en) 3 ] 3+ → No. of G.I. = 0

For [Cr(en) 2 Br 2 ] + → No. of G.I. = 2

For [Pt (en) Cl 2 ] → No. of G.I. = 0

For [Co(NH 3 ) 3 (NO 2 ) 3 ] → No. of G.I. = 2

Hence sum of Geometrical isomers = 4.
