Lewis structure
Draw the Lewis structure of ethanol. 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 oxygen (n_O, val = 6) atoms: 2 n_C, val + 6 n_H, val + n_O, val = 20 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), hydrogen (n_H, full = 2), and oxygen (n_O, full = 8): 2 n_C, full + 6 n_H, full + n_O, full = 36 Subtracting these two numbers shows that 36 - 20 = 16 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 8 bonds and hence 16 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 20 - 16 = 4 electrons left to draw: Answer: | |
