Although we usually don't show lone pairs on skeletal structures, sometimes it's necessary, for example, to show how a reaction will occur. Draw in any lone pairs in the structure below. Note: you may need to redraw parts of the structure to show atoms and bonds within a group before you can add any missing lone pairs HS HS

4. Draw two other reasonable resonance structures of this compound. Label each resonance form, including the one provided, as either "major" or "minor." :O: H3C H H

Fill out this paper front sheet please.

6. Given the following electronegativities for the atoms below, circle the compound that contains the MORE POLAR bond (indicated) of each pair. Indicate the dipole for that bond. Relative electronegativities: Li = 1.0 C = 2.5 0=3.5 Cl = 3.0 H=2.1 Si = 1.8 H₂C-Cl or Cl-ci c) (CH³)³Si-Hor H³C-H b) H₂C-OH or H₂C-Li d) H₂C-H or H- H-CI
