Which among the following is used in the treatment of cancer?

A molecule $$(X)$$ has (i) four sigma bonds formed by the overlap of $$sp^{2}$$ and $$s$$ orbitals; (ii) one sigma bond formed by $$sp^{2}$$ and $$sp^{2}$$ - orbitals and (iii) one $$\pi-bond$$ formed by $$p_{z}$$ and $$p_{z}$$ orbitals. Which of the following is $$X$$?

The total number of possible coordination isomer for the given compound $$[Pt(NH_3)_4Cl_2][PtCl_4]$$ is?

The octahedral complex $$CoSO_4Cl_5\,NH_3$$ exists in two isomeric forms $$X$$ and $$Y$$. Isomers $$X$$ reacts with $$AgNO_3$$ to give a white precipitate, but does not react with $$BaCl_2$$. Isomer $$Y$$ gives white precipitate with $$BaCl_2$$ but does not react with $$AgNO_3$$.
Isomers $$X$$ and $$Y$$ are: 

Brown ring complex known as:

Which complex among the following gives a white precipitate on treatment with an aqueous solution of barium chloride?

The complexes $$[Cr(NH_3)_6][Co(CN)_6]$$ and $$[Co(NH_3)_6][Cr(CN)_6]$$ are not the example of?

Choose the correct statement regarding the complexes X and Y:
(I) Both complexes have the same six geometrical isomer.
(II) Both complexes have nearly the same conductivity in $$H_2O$$.
(III) In both complexes, $$NH_3$$ is involved only to secondary valency.
(IV) In both complexes, electronic configuration of $$t_{2g}$$ is same.

VSEPR theory suggest a small departure from $$ 109^0 28'$$ for $$ NH_3 $$ molecule. The H-N-H bond angle has been found to be $$ 107^0 $$ what kind of hybrid orbital will be occupied by the non -bonding pair of electron?

Match the complex species given in Column-I with the possible isomerism given in Column-II and assign the correct code.
