Although fluorine is more electronegative than oxygen,the ability of oxygen to stabilize higher oxidation states exceeds that of fluorine. Why?

Which of the following hydrides of Group $16$ elements has the highest reducing property?

State the electronic configurations of group-$16$ elements.

Identify the incorrect statement regarding ozone $(O_3)$.

How is $O_3$ estimated quantitatively?

Given below are two statements: Statement $I$: The covalency of oxygen is generally two but it can exceed up to four. The oxidation state of oxygen in $SO_2$ is $-2$ and in $OF_2$ it is $+2$. Statement $II$: The anomalous behaviour of oxygen when compared to the other elements of group $16$ is due to its small size and high electronegativity. In the light of the above statements, choose the correct answer from the options given below.
