Lewis structure
Draw the Lewis structure of (1-bromovinyl)trimethylsilane. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds: Count the total valence electrons of the bromine (n_Br, val = 7), carbon (n_C, val = 4), hydrogen (n_H, val = 1), and silicon (n_Si, val = 4) atoms: n_Br, val + 5 n_C, val + 11 n_H, val + n_Si, val = 42 Calculate the number of electrons needed to completely fill the valence shells for bromine (n_Br, full = 8), carbon (n_C, full = 8), hydrogen (n_H, full = 2), and silicon (n_Si, full = 8): n_Br, full + 5 n_C, full + 11 n_H, full + n_Si, full = 78 Subtracting these two numbers shows that 78 - 42 = 36 bonding electrons are needed. Each bond has two electrons, so in addition to the 17 bonds already present in the diagram add 1 bond. 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 1 bond by pairing electrons between adjacent highlighted atoms: Answer: | |
