1, 1, 2-trimethylcyclopropane

formula | C_6H_12 name | 1, 1, 2-trimethylcyclopropane alternate names | cyclopropane, 1, 1, 2-trimethyl- mass fractions | C (carbon) 85.6% | H (hydrogen) 14.4%

Draw the Lewis structure of 1, 1, 2-trimethylcyclopropane. Start by drawing the overall structure of the molecule: Count the total valence electrons of the carbon (n_C, val = 4) and hydrogen (n_H, val = 1) atoms: 6 n_C, val + 12 n_H, val = 36 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 + 12 n_H, full = 72 Subtracting these two numbers shows that 72 - 36 = 36 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 18 bonds and hence 36 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 36 - 36 = 0 electrons left to draw and the diagram is complete: Answer: | |
