Question

Please explain why H2O has single bond and CO2 double bond.

Answer 1

Note that carbon dioxide has two covalent bonds between each oxygen atom and the carbon atom, which is shown here as two lines and referred to as a double bond. When molecules are symmetrical, however, the atoms pull equally on the electrons and the charge distribution is uniform.
