The electronegativity of aluminium is similar to

How would you react to the statement that the electronegativity of $N$ on the Pauling scale is $3.0$ in all nitrogen compounds?

In the compound $M-O-H$,the $M-O$ bond will be broken if

The $EN$ (Electronegativity) of element $A$ is $E_1$ and its $IP$ (Ionization Potential) is $E_2$. Hence,the $EA$ (Electron Affinity) will be:

Given below are two statements:
Statement $I$: The correct order of electronegativity of fluorine, oxygen and nitrogen is $F > O > N$.
Statement $II$: The oxidation state of oxygen in $OF_2$ is $+2$ and in $Na_2O$ is $-2$.

Which of the following statements is incorrect?
