11. (draw the skeletal structure) You are given an alkene in the assignment (trans-hex-3-ene) Treat this alkene with peroxyacetic acid. Before submitting your structure, make sure you have followed the input format for showing the stereochemistry of rings. You need to make sure the tapered end of the wedge or dashed bond is connected to the ring. You should not be drawing the carboxylic acid by-product.

1) In the Lewis structure of $\mathrm{HCO}_{3}^{-}$, all three oxygen atoms are attached to the carbon atom, and the hydrogen is attached to one of the oxygen atoms. After assigning all the valence electrons, the carbon has just six electrons, so it is short of a full octet. At that point you need to convert a lone pair on one of the oxygens into another bond between that oxygen and the carbon. The problem is, there are two different types of oxygen here: the two oxygens with just a single bond to carbon, and the one oxygen with a bond to carbon and a bond to hydrogen. a. Draw the Lewis structure you would get if you had used a lone pair from one of the two oxygens that isn't bonded to the hydrogen. (1 pt.) b. Draw the Lewis structure you would get if, instead, you had used a lone pair from the oxygen that is bonded to the hydrogen. (1 pt.) c. Explain why the first of those two Lewis structures is the more stable one. (1 pt.) a.) $\mathrm{HCO}_{3}^{-}: \theta$ b.) c.)?
