So organic chemistry is essentially the study of covalent bonds. And covalent bonds are formed by the overlap of atomic orbitals. And that means in order to understand what covalent bonds are, we must first understand what atomic orbitals are. So let's begin. So here we have so here we have Boris model. Now, Boris'model is essentially a depiction of the nucleus, the protons found in the nucleus and the electrons found orbiting our nucleus.
