Question

In the figure, $stack B C with bar on top parallel to stack D E with bar on top comma angle A C B equals 60 to the power of ring operator end exponent comma angle A E D equals 80 to the power of ring operator end exponent text and end text angle B A C equals 90 to the power of ring operator end exponent. text Then end text angle B A E equals ?$

20°
30°
70°
110°

The correct answer is: 70°

S₁ : Generally square planar complexes show geometrical isomerism but do not exhibit optical isomerism because they do not possess planer of symmetry.
S₂ : $capital delta subscript t end subscript equals fraction numerator 4 over denominator 9 end fraction capital delta subscript 0 end subscript$
S₃ : In octahedral complexes each electron entering the t_2g orbitals stabilizes the complex ion by 0.4 $capital delta subscript 0 end subscript$ and each electron entering the e.gorbital destabilizes the complex by an amount of 0.6 Δ₀.
