Explain the nature of the covalent bond using the bond formation in CH3Cl.
Covalent bond/s is formed by sharing of electrons so that the combining atom/s complete their outermost shell. In CH3Cl, this happens as follows:
Three hydrogen atoms complete (K = 1 + 1 = 2) their shells by sharing three electrons (one electron each) of carbon atom. Chlorine complete its outer shell (L = 7 + 1 = 8) by sharing its one out of seven electrons with one electron of carbon atom. Thus carbon atom shares in all its four electrons with three of three hydrogen atoms and one of chlorine atom and completes its outer shell (L = 4 + 3 + 1 = 8).
