Lewis structure
Draw the Lewis structure of 1-chloro-1-propene. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: 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 + 5 n_H, val = 24 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 + 5 n_H, full = 42 Subtracting these two numbers shows that 42 - 24 = 18 bonding electrons are needed. Each bond has two electrons, so in addition to the 8 bonds already present in the diagram add 1 bond. To minimize formal charge carbon wants 4 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 1 bond by pairing electrons between adjacent highlighted atoms: Answer: | |
