Solution : Step 1 : Molecular compounds are also called as covalent compounds. Molecular compounds are compounds which are composed of different types of atoms i.e they contain two or more nonmetals in them. They are compounds in which the elements share electrons via covalent bonds. The number of different types of atoms present in the molecular compound is represented by the chemical formula. This chemical formula is called as Molecular formula. Molecular formula is a gives the total number of atoms of each element in each molecule of a substance. These definite numbers of atoms present in a molecule are represented as subscripts in the molecular formula. For example : Hydrogen peroxide is a molecular compound and has the molecular formula H O . 2 2 Hydrogen peroxide is made of two hydrogen atoms and two oxygen atoms.
