formula | C_35H_38Cl_2N_8O_4 name | itraconazole IUPAC name | 2-butan-2-yl-4-[4-[4-[4-[[(2S, 4S)-2-(2, 4-dichlorophenyl)-2-(1, 2, 4-triazol-1-ylmethyl)-1, 3-dioxolan-4-yl]methoxy]phenyl]piperazin-1-yl]phenyl]-1, 2, 4-triazol-3-one alternate names | itrizole | oriconazole | sporanox mass fractions | C (carbon) 59.6% | Cl (chlorine) 10% | H (hydrogen) 5.43% | N (nitrogen) 15.9% | O (oxygen) 9.07%

Draw the Lewis structure of itraconazole. 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), hydrogen (n_H, val = 1), nitrogen (n_N, val = 5), and oxygen (n_O, val = 6) atoms: 35 n_C, val + 2 n_Cl, val + 38 n_H, val + 8 n_N, val + 4 n_O, val = 256 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), chlorine (n_Cl, full = 8), hydrogen (n_H, full = 2), nitrogen (n_N, full = 8), and oxygen (n_O, full = 8): 35 n_C, full + 2 n_Cl, full + 38 n_H, full + 8 n_N, full + 4 n_O, full = 468 Subtracting these two numbers shows that 468 - 256 = 212 bonding electrons are needed. Each bond has two electrons, so in addition to the 93 bonds already present in the diagram add 13 bonds. To minimize formal charge oxygen wants 2 bonds, nitrogen wants 3 bonds, and carbon wants 4 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 13 bonds by pairing electrons between adjacent highlighted atoms. Note that the six atom rings are aromatic, so that the single and double bonds may be rearranged: Answer: | |
