Question

Which of the following is true about the complex $\left[\right.PtCl_{2}\left(\right.H_{2}O\left.\right)\left(\right.NH_{3}\left.\right)\left]\right.$ ?

• A. It exhibits geometrical isomerism
• B. It is paramagnetic complex
• C. Its geometry is tetrahedron
• D. Ptatinum is $sp^{3}$ hybridised

Answer 1

Answer: (A)

This complex exhibits geometrical isomerism as it is $Ma_{2}bc$ type complex. Rest other things given here are wrong about it as

$\left[ PtCl _{2}\left( NH _{3}\right)( HO )_{2}\right] ;$ Pt-oxidation state $+2$ Valence configuration $=5 d ^{8}$

This complex is diamagnetic as it is an inner orbital complex with dsp $^{2}$ -hybridisation and square planar shape.
