24. Carbon dioxide : Carbon has four valence electron. It shares two electron with one of the oxygen and two electrons with other atom of oxygen to form double covalent bond.
25. Methyl chloride (CH3Cl) : Carbon has four valence electrons. It shares one electron with chlorine atom and one electron with each of three hydrogen atoms forming four single bond.
26. Carbon tetrachloride (CCl4) : Carbon shares one electron with each of four chlorine atoms forming four single covalent bonds.
