Question

If true enter ${ 1 } $, else enter ${ 0 } $.
Covalent bonds are directional and ionic bonds are non-directional
(a) ${ 1 }$
(b) ${ 0 } $
(c) Both
(d) None of these

Answer 1

Hint: Covalent bond is defined as the bond which is formed by mutual sharing of electrons. Ionic bond is defined as the bond which is formed by the transfer of electrons from metal to non-metal. It occurs between oppositely charged ions.

Complete step-by-step solution:
> Covalent bonds are formed by the overlapping of atomic orbitals.So, the direction of overlapping gives direction of bonds,i.e, a shared pair of electron/ electrons are localized between two atoms. Hence, covalent bond is a directional bond.
> In ionic compounds, there is no overlapping of atomic orbitals. Each ion has its influence in all the directions. It means it is surrounded by a number of oppositely charged ions with no definite direction. Thus, ionic bonds are non-directional.

Hence, the above statement is true.Therefor answer is (A)

Additional Information: Polar Bonding:- A covalent bond formed between two different atoms, with different electronegativities is known as Polar covalent bond.
Non-polar bonding:- A covalent bond formed between two like atoms is known as Non-Polar bond. Here, the electronegativity difference is zero.

Note: The possibility for the mistake is that you can choose the option (b). You may think covalent bonds are non-directional and ionic bonds are directional. But it’s not true because in covalent bonds both sigma and pi bonding occurs and its directional while in ionic, an ion has the same attraction from all directions.
