Chapter : 6. Carbon and Its Compound

Single Covalent Bond

12. Single Covalent Bond : It is a bond formed by sharing of one electron by each of the atoms. It is represented by a line between two atoms.
13. Hydrogen Fluoride : When one hydrogen atom shares one electron with one electron of fluorine, hydrogen acquires two electrons whereas fluorine acquires 8 electrons and becomes stable. They form single covalent bond.

(Single Covalent bond between hydrogen and fluorine)
14. Water : In formation of H2O , each hydrogen atoms shares one electron with oxygen atom so that oxygen completes its octet and hydrogen acquires nearest nobles gas configuration.

15. Ammonia : Nitrogen has five valence electrons. It shares one electron with each of the three hydrogen atoms to form NH3.

16. Methane : Carbon has four valence electrons. It needs four electrons to complete its octet. It shares four electrons with four hydrogen atoms and forms four single covalent bonds.
