I'm not quite sure how to do arrow pushing for these molecules? I know they are probably easy, but I don't quite understand.
Link to the diagrams (there are 3 questions): http://i10.photobucket.com/albums/a120/SakamotoKumiko/organochem.jpg
I'm not sure if these diagrams are correct because my friend said some of these are impossible, but that is how my lab TA drew them. For the last reaction, I thought I had to draw 2 different arrow pushings for both products but my friend said no, you can do it in one step. I'm not sure. I know I'm not the smartest, but I would be nice if you can help. Thank You In Advanced!
