Carbon and Its Compound


Explain the nature of the covalent bond using the bond formation in CH3Cl.


The covalent bond is the bond that is formed by the sharing of electrons between two or more atoms. The atomic number of carbon is 6 and its electronic configuration is (2, 4) while the atomic number of chlorine is 17 and its electronic configuration is (2, 8, 7). This means that carbon needs four electrons while chlorine and hydrogen need one electron each to complete its octet.

The structure of chloromethane forms when the carbon shares its electron with three hydrogen atoms to form three C-H bonds and its one electron with a chlorine atom to form one C-Cl bond. Hence, the structure of CH3Cl will be as follows:
