Lewis structure
Draw the Lewis structure of 1, 5-diiodopentane. Start by drawing the overall structure of the molecule: Count the total valence electrons of the carbon (n_C, val = 4), hydrogen (n_H, val = 1), and iodine (n_I, val = 7) atoms: 5 n_C, val + 10 n_H, val + 2 n_I, val = 44 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), hydrogen (n_H, full = 2), and iodine (n_I, full = 8): 5 n_C, full + 10 n_H, full + 2 n_I, full = 76 Subtracting these two numbers shows that 76 - 44 = 32 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 16 bonds and hence 32 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 44 - 32 = 12 electrons left to draw: Answer: | |
