Question

explain the nature of the covalent bond by using the bond formula in CH3Cl ?​

Answer 1

The atomic number of carbon is 6 and its electronic configuration is 2, 4. Thus, there are 4 electrons in the valence shell of carbon and it needs 4 more to complete its octet. Hydrogen, on the other hand has one electron in its valence shell and needs one more in order to complete its duplet. Also, the atomic number of chlorine is 17 and its electronic configuration is 2, 8, 7. It needs one electron more in order to complete its octet. Carbon therefore shares one of its four valence electrons with chlorine and remaining three with three hydrogen atoms. Thus, carbon forms one covalent bond to chlorine and three covalent bonds with three hydrogen atoms.
