Match List I with List II

Choose the correct answer from the options given below:

Given below are two statements: Statement I: $$N(CH_3)_3$$ and $$P(CH_3)_3$$ can act as ligands to form transition metal complexes. Statement II: As N and P are from same group, the nature of bonding of $$N(CH_3)_3$$ and $$P(CH_3)_3$$ is always same with transition metals. In the light of the above statements, choose the most appropriate answer from the options given below:

For the given hypothetical reactions, the equilibrium constants are as follows: $$X \rightleftharpoons Y; K_1 = 1.0$$, $$Y \rightleftharpoons Z; K_2 = 2.0$$, $$Z \rightleftharpoons W; K_3 = 4.0$$. The equilibrium constant for the reaction $$X \rightleftharpoons W$$ is

Among the following halogens $$F_2, Cl_2, Br_2$$ and $$I_2$$. Which can undergo disproportionation reactions?

Thiosulphate reacts differently with iodine and bromine in the reactions given below: $$2S_2O_3^{2-} + I_2 \rightarrow S_4O_6^{2-} + 2I^-$$, $$S_2O_3^{2-} + 5Br_2 + 5H_2O \rightarrow 2SO_4^{2-} + 4Br^- + 10H^+$$. Which of the following statement justifies the above dual behaviour of thiosulphate?

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R: Assertion A: The stability order of +1 oxidation state of Ga, In and Tl is $$Ga < In < Tl$$. Reason R: The inert pair effect stabilizes the lower oxidation state down the group. In the light of the above statements, choose the correct answer from the options given below:

Which of the following are aromatic?
