Draw the Lewis structure of aluminum carbide. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: Count the total valence electrons of the aluminum (n_Al, val = 3) and carbon (n_C, val = 4) atoms: 4 n_Al, val + 3 n_C, val = 24 Calculate the number of electrons needed to completely fill the valence shells for aluminum (n_Al, full = 6) and carbon (n_C, full = 8): 4 n_Al, full + 3 n_C, full = 48 Subtracting these two numbers shows that 48 - 24 = 24 bonding electrons are needed. Each bond has two electrons, so in addition to the 6 bonds already present in the diagram add 6 bonds. To minimize formal charge aluminum wants 3 bonds and carbon wants 4 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 6 bonds by pairing electrons between adjacent highlighted atoms: Answer: | |
