The nature of the bond formed between two elements depends on the

Which of the following sets of atoms is arranged in order of increasing electronegativity?

Arrange $F$,$Cl$,$O$,and $N$ in the decreasing order of electronegativity.

Which of the following order is correct for the property mentioned in brackets?

Aqueous solutions of two compounds $M_1OH$ and $M_2OH$ are prepared in two different beakers. If the $EN$ of $M_1 = 3.4$,$EN$ of $M_2 = 1.2$,$EN$ of $O = 3.5$,and $EN$ of $H = 2.1$,then the nature of the two solutions will be:

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