Which brand in each of the following pairs has the greater ionic character?
msp;

(a)
Interpretation:
Among the given pair of bonds, the bond that possesses the greater ionic character is to be identified.
Concept Introduction:
The ability that is possessed by an atom to attract the bonding pair of electrons towards itself is known as electronegativity. The electronegativity decreases while going down the group and increases while moving left to right in the period.
In ionic compounds, the bonding is formed by the complete transfer of the electrons between the atoms to achieve the stable electron configuration like the noble gases. The higher electronegativity difference between two atoms of a compound corresponds to the greater ionic character of the compound.
