Question

Ionic bond is not present in which of the following compounds?

• A. $NaOH$
• B. $HCl$
• C. $K_{2}S$
• D. $LiH$

Answer 1

The correct option is B $HCl$

$NaOH:$ The metallic sodium atom is attached to oxygen which is a non-metal. Hence $NaOH$ is an ionic compound due to the high electronegativity difference between sodium and oxygen.

$HCl:$ Hydrogen and chlorine are both nonmetals and hence $HCl$ is a covalent compound.

$K_{2}S:$ Potassium is a metal and sulphur is a non-metal. Therefore, $K_{2}S$ is an ionic compound.

$LiH:$ Lithium is a metal and hydrogen is a non-metal. Therefore, $LiH$ is an ionic compound.

Hence, $HCl$ is the non-ionic compound out of the given compounds.
