Lewis structure
Draw the Lewis structure of 1-chloropropane. Start by drawing the overall structure of the molecule: Count the total valence electrons of the carbon (n_C, val = 4), chlorine (n_Cl, val = 7), and hydrogen (n_H, val = 1) atoms: 3 n_C, val + n_Cl, val + 7 n_H, val = 26 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), chlorine (n_Cl, full = 8), and hydrogen (n_H, full = 2): 3 n_C, full + n_Cl, full + 7 n_H, full = 46 Subtracting these two numbers shows that 46 - 26 = 20 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 10 bonds and hence 20 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 26 - 20 = 6 electrons left to draw: Answer: | |
