How do molecular compounds bond?

Hint :In order to answer this question, to know the type of bond present in molecular compounds, we should go through all types of bonds and the properties of molecular compounds, whether which bond is suitable for the molecular compounds.

Complete Step By Step Answer:
Molecular or covalent compounds bond to each other by intermolecular forces of attraction.
These forces involve electrostatic attractions between the negative and positive charges in neighbouring particles.
Covalent or molecular compounds contain atoms held together by covalent bonds. These bonds form when the atoms share electrons because they have similar electronegativity values.
So, now we will discuss the covalent bond because the molecular compounds are bound together by covalent bonds. So, a covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
In chemistry, the interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons. A bond forms when the bonded atoms have a lower total energy than that of widely separated atoms.

Note :
A covalent bond is a type of chemical bond that forms when two atoms share an electron pair between them. It is named as a “molecular bond”. These bonds form when “shared pairs” or “bonding pairs” exist between atoms.
