Interpretation:
The rank has to be given to the given compounds,
Concept Introduction:
An electronegativity of an atom gives information about the strength that the atom has for attracting a pair of shared electrons. The greater the attraction for a pair of shared electrons when the electronegativity value is high. Consequently, when two different electronegative atoms share a pair of electrons, one atom becomes partially positive and the other atom becomes partially negative due to the attractive forces for the pair of electrons.
The larger is the electronegativity difference between the atoms, the more polar will be the bond between the atoms.
