Date Laboratory Exercises Using a molecular modeling kit, construct models of each of the compounds in the tables below. Complete the following three tables by first drawing a simple sketch of the molecule showing which atoms are attached to each other, the number of bonds between each pair of atoms, and any nonbonding electrons. Then, draw the molecule again showing the actual shape and the angles between the atoms as accurately as you can. The first one has been completed...
