Lewis structure
Draw the Lewis structure of dibromoneopentyl glycol. 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), hydrogen (n_H, val = 1), and oxygen (n_O, val = 6) atoms: 2 n_Br, val + 5 n_C, val + 10 n_H, val + 2 n_O, val = 56 Calculate the number of electrons needed to completely fill the valence shells for bromine (n_Br, full = 8), carbon (n_C, full = 8), hydrogen (n_H, full = 2), and oxygen (n_O, full = 8): 2 n_Br, full + 5 n_C, full + 10 n_H, full + 2 n_O, full = 92 Subtracting these two numbers shows that 92 - 56 = 36 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 18 bonds and hence 36 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 56 - 36 = 20 electrons left to draw: Answer: | |
