Answer:

Lithium Fluoride (LiF) is not an example of covalent bond. It is an ionic compound.

Explanation:

Lithium fluoride, an inorganic compound has the chemical formula LiF. It is most widely used as a flux in the production of ceramics, such as enamels, glasses and glazes. It is also used in welding and brazing fluxes and molten salt chemistry in metallurgy.

LIF, is a salt which is formed from the neutralization of the strong base lithium hydroxide with weak acid hydrofluoric acid, HF.

The correct answer will be option 4.

A covalent bond is formed by sharing of electrons while an ionic bond is formed by gaining and losing electrons.

1)In CF₄, the bond is formed by sharing 4 electrons of carbon with 1 electron of each fluorine atom.

2)In HF, hydrogen, and fluorine share their 1 electron each to complete duplet and octet.

3)In NH₃, 3 valence electrons of nitrogen are shared with 1 electron each of hydrogen.

4)In LiF, Li loses its 1 electron. The electron lost by Li is gained by fluorine to form the ionic bond.
