Lewis structure
Draw the Lewis structure of triethylaluminum. Start by drawing the overall structure of the molecule: Count the total valence electrons of the aluminum (n_Al, val = 3), carbon (n_C, val = 4), and hydrogen (n_H, val = 1) atoms: n_Al, val + 6 n_C, val + 15 n_H, val = 42 Calculate the number of electrons needed to completely fill the valence shells for aluminum (n_Al, full = 6), carbon (n_C, full = 8), and hydrogen (n_H, full = 2): n_Al, full + 6 n_C, full + 15 n_H, full = 84 Subtracting these two numbers shows that 84 - 42 = 42 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 21 bonds and hence 42 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 42 - 42 = 0 electrons left to draw and the diagram is complete: Answer: | |
