(a)
Interpretation:
The bonding nature between atoms of
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.
