Example of arrangement of
molecules of compounds​

Molecular compounds are inorganic compounds that take the form of discrete molecules. Examples include such familiar substances as water (H2O) and carbon dioxide (CO2). These compounds are very different from ionic compounds like sodium chloride (NaCl).

Explanation:

Drawing the pertaining lewis structure of the covalent compound in question can give you a good mental picture of how the constituent atoms are arranged within the compound.

In other words, draw a lewis structure of the molecular compound in question to see how it's constituent atoms are arranged.

To draw lewis structures, count the number of valence electron about each constituent atom and place the atom which is least electronegative in the center of the compound.
