Question

Which of the following is⁄are correct?

• A. Greater the electronegativity difference in the oxide more will be basic character
• B. Lesser the electronegativity difference in the oxide more will be the acidic character
• C. Greater the electronegativity difference in the bond in gaseous compound more will be stability of the bond
• D. All of the above are correct

Answer 1

The correct option is D All of the above are correct

Electronegativity increases as move from the left to right in the periodic table.
If the electronegativity difference is high, the metal atom gives its electron to oxygen and forms ionic bond. Upon dissolution in water, it will give a base .
Example: $N{a}_{2}O+H_{2}O\to NaOH$
If the electronegativity difference is small, the metal atom shares the electron by a covalent bond. Upon dissolution in water, it will give acid.
Example: $C{O}_2+H_{2}O\to H_{2}C{O}_3$
Greater the electronegativity difference, the metal forms an ionic bond which is stronger than a covalent bond.
