Poll

How are you feeling about lewis structures?

• I can draw them as long as they follow the rules.

• I remember the rules but have trouble drawing them. 

• Who is Lewis and how did he get a structure?

Multiple Choice

The acronym VSEPR stand for

• very strong electron pair repulsion.

• varied symmetry electrostatic proton reaction.

• venomous snakes enjoy pink ribbons.

• valence shell electron pair repulsion.

Multiple Choice

Any molecule with only two atoms must be linear. Three-atom molecules such as BeCl₂ can also be linear. For linear molecules, the bond angle is

• $$360\degree$$

• $$180\degree$$

• $$120\degree$$

• $$90\degree$$
