Lewis structure
Draw the Lewis structure of trans-decahydronaphthalene. 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: 10 n_C, val + 18 n_H, val = 58 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 + 18 n_H, full = 116 Subtracting these two numbers shows that 116 - 58 = 58 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 29 bonds and hence 58 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 58 - 58 = 0 electrons left to draw and the diagram is complete: Answer: | |
