Lewis structure
Draw the Lewis structure of 1-decene. 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: 10 n_C, val + 20 n_H, val = 60 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8) and hydrogen (n_H, full = 2): 10 n_C, full + 20 n_H, full = 120 Subtracting these two numbers shows that 120 - 60 = 60 bonding electrons are needed. Each bond has two electrons, so in addition to the 29 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: | |
