Lewis structure
![Draw the Lewis structure of cyclohexene. 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) and hydrogen (n_H, val = 1) atoms: 6 n_C, val + 10 n_H, val = 34 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8) and hydrogen (n_H, full = 2): 6 n_C, full + 10 n_H, full = 68 Subtracting these two numbers shows that 68 - 34 = 34 bonding electrons are needed. Each bond has two electrons, so in addition to the 16 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: | |](../image_source/fbc517cf751bc4580871b0c0af4b77ce.png)
