The Lewis structure for CO 2 molecule is to be drawn. Concept introduction: The number of valence electrons of an atom is equal to the group number of the periodic table to which it belongs. Bonding atoms attain a stable electronic configuration, which generally has eight electrons in the valence shell. The steps for drawing a covalent Lewis structure are as follows: Write the skeletal structure of the molecule. Atom that have the lowest electronegativity will be the central atom. Add the number of valence electrons of each atom in the molecule to determine the total number of electrons in the molecule. Place the electrons as dots to complete the octets of the atoms. If the central atom has not obtained an octet, multiple bonds can be formed.

" is The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: :Ö: HO + Bicarbonate is crucial for the control of body pH (for example, blood pH: 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.
