Lewis structure
Draw the Lewis structure of amyl bromide. 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), and hydrogen (n_H, val = 1) atoms: n_Br, val + 5 n_C, val + 11 n_H, val = 38 Calculate the number of electrons needed to completely fill the valence shells for bromine (n_Br, full = 8), carbon (n_C, full = 8), and hydrogen (n_H, full = 2): n_Br, full + 5 n_C, full + 11 n_H, full = 70 Subtracting these two numbers shows that 70 - 38 = 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 38 - 32 = 6 electrons left to draw: Answer: | |
