formula | C_19H_17NO name | 4-methoxytriphenylamine IUPAC name | 4-methoxy-N, N-di(phenyl)aniline alternate names | 4-methoxy-N, N-di(phenyl)aniline | 4-methoxy-N, N-diphenylaniline | (4-methoxyphenyl)-di(phenyl)amine mass fractions | C (carbon) 82.9% | H (hydrogen) 6.22% | N (nitrogen) 5.09% | O (oxygen) 5.81%

Draw the Lewis structure of 4-methoxytriphenylamine. 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), hydrogen (n_H, val = 1), nitrogen (n_N, val = 5), and oxygen (n_O, val = 6) atoms: 19 n_C, val + 17 n_H, val + n_N, val + n_O, val = 104 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), hydrogen (n_H, full = 2), nitrogen (n_N, full = 8), and oxygen (n_O, full = 8): 19 n_C, full + 17 n_H, full + n_N, full + n_O, full = 202 Subtracting these two numbers shows that 202 - 104 = 98 bonding electrons are needed. Each bond has two electrons, so in addition to the 40 bonds already present in the diagram add 9 bonds. 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 9 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: | |
