Vedclass · Answer

(C) Statement $(i)$ is correct: Oxygen shows $-2$ oxidation state in most compounds,$-1$ in peroxides (e.g.,$H_2O_2$),$+1$ in $O_2F_2$,and $+2$ in $OF_2$.Statement $(ii)$ is incorrect: The thermal stability of group $16$ hydrides decreases down the group due to the increase in bond length and decrease in bond dissociation enthalpy. The correct order is $H_2O > H_2S > H_2Se > H_2Te$.Statement $(iii)$ is correct: The reducing nature increases down the group as the thermal stability of the hydrides decreases. The order is $H_2S < H_2Se < H_2Te$.
