Consider the following statements
S1 : Generally square planar complexes show geometrical isomerism but do not exhibit optical isomerism because they do not possess plane of symmetry
S2:Δt=49Δo
S3 : In octahedral complexes each electron entering the t2g orbtials stabilizes the complex ion by 0.4 Δo and each electron entering the eg orbital destabilizes the complex by an amount of 0.6 Δo
