Lewis structure
Draw the Lewis structure of 1, 2-dibromo-1, 1, 2-trichloroethane. Start by drawing the overall structure of the molecule: Count the total valence electrons of the bromine (n_Br, val = 7), carbon (n_C, val = 4), chlorine (n_Cl, val = 7), and hydrogen (n_H, val = 1) atoms: 2 n_Br, val + 2 n_C, val + 3 n_Cl, val + n_H, val = 44 Calculate the number of electrons needed to completely fill the valence shells for bromine (n_Br, full = 8), carbon (n_C, full = 8), chlorine (n_Cl, full = 8), and hydrogen (n_H, full = 2): 2 n_Br, full + 2 n_C, full + 3 n_Cl, full + n_H, full = 58 Subtracting these two numbers shows that 58 - 44 = 14 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 7 bonds and hence 14 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 44 - 14 = 30 electrons left to draw: Answer: | |
