Question
Which one of the following is incorrect according to the ionic compound?
- They have high melting and boiling point
- Ionic bond is formed by transferring of electrons
- Ionic bond is formed by sharing of electrons
- Ionic bonds are the good conductors of electricity
Hint:
Ionic bonds are formed by the attraction between oppositely charged ions due to electron exchange.
The correct answer is: Ionic bond is formed by sharing of electrons
- Ionic bonds are stronger bonds hence they have high boiling and melting points.
- Ionic bonds can break to form ions which conduct electricity.
- Covalent bonds are formed by sharing of electrons whereas ionic bonds are formed by electron exchange.
