Question

Non Directional bond is present in:
A. $KF$
B. ${{H}_{2}}$
C. ${{H}_{2}}O$
D. BOTH A AND B

Answer 1

Hint: Ionic bonds and electrovalent bonds are called non-directional bonds. In a non-directional bond there is no special type of geometry present.

Complete step-by-step answer:
Ionic bonds are the known type of chemical bonds which have the presence of the electrostatic force of attraction in between the two of the oppositely charged ions which is also known as the primary interaction between the ionic compounds. Ionic bonds are also said to be electrovalent bonds.
Ionic bond is the main type of bond as well as covalent and metallic bonds too. Ions are the known atoms which carry electrostatic charge.
Covalent bond is directional in nature as it has a definite path and is formed due to overlapping of the half-filled orbitals of the atom. Whereas in ionic bonds every single ion is crowded by many of the oppositely charged ions so there is no direction present in it.
Non-directional bonds are ionic bonds which are made from the positive and negative charges. In the structure of KF, we will see that K is a metal with positive charge and F is a non-metal with negative charge. So KF shows an ionic bond and it is also a non-directional bond.

The correct answer is A.

In ${{H}_{2}}$ there is a covalent bond which is present which forms by the sharing of electrons. So it is not a non-directional bond.
${{H}_{2}}O$ is also formed by the sharing of electrons so it is also a non-directional bond.

Note: Charge is uniform in all directions in ionic bonds so it is also known as non-directional bonds. Covalent bonds are directional bonds. Molecules which have the presence of covalent bonds have their particular shapes.
