formula | C_9H_12BBrO_3 name | 3-bromo-2-isopropoxyphenylboronic acid IUPAC name | (3-bromo-2-isopropoxyphenyl)boronic acid alternate names | (3-bromo-2-isopropoxy-phenyl)boronic acid | (3-bromo-2-propan-2-yloxy-phenyl)boronic acid | (3-bromo-2-propan-2-yloxyphenyl)boronic acid mass fractions | B (boron) 4.18% | Br (bromine) 30.9% | C (carbon) 41.8% | H (hydrogen) 4.67% | O (oxygen) 18.5%

Draw the Lewis structure of 3-bromo-2-isopropoxyphenylboronic acid. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: Count the total valence electrons of the boron (n_B, val = 3), bromine (n_Br, val = 7), carbon (n_C, val = 4), hydrogen (n_H, val = 1), and oxygen (n_O, val = 6) atoms: n_B, val + n_Br, val + 9 n_C, val + 12 n_H, val + 3 n_O, val = 76 Calculate the number of electrons needed to completely fill the valence shells for boron (n_B, full = 6), bromine (n_Br, full = 8), carbon (n_C, full = 8), hydrogen (n_H, full = 2), and oxygen (n_O, full = 8): n_B, full + n_Br, full + 9 n_C, full + 12 n_H, full + 3 n_O, full = 134 Subtracting these two numbers shows that 134 - 76 = 58 bonding electrons are needed. Each bond has two electrons, so in addition to the 26 bonds already present in the diagram add 3 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 3 bonds by pairing electrons between adjacent highlighted atoms. Note that the six atom ring is aromatic, so that the single and double bonds may be rearranged: Answer: | |
