We need to overcome this to obtain a stable Lewis structure for C, It can be seen that all the atoms in the above figure fulfill their octet requirements. As a result, the atoms in a molecule tend to separate as far as they can because their bonds repel each other. In this step, we need to determine the hybridization number of C2H4. Formal charge = (Valence electrons unbonded electrons 1/2 bonded electrons). In order to draw the lewis structure of C2H4, first of all you have to find the total number of valence electrons present in the C2H4 molecule. Therefore, the four Hydrogen atoms contribute 1 x 4 = 4 valence electrons. C2H4 molecular weight. Complete central atom octet and make covalent bond if necessary. 3)C2H4Br2-cng thc nghim thu gn Br-CH2-CH2-Br.
