THIS IS THE THIRD TIME I'VE SENT THOSE QUESTIONS SO PLEASE DONT RESEND THE SAME STUFF, ITS NOT HELPING ME!!! I ALSO ALREADY TRIED TO DRAW THE MECHANISM MYSELF, SO IF ITS RIGHT PLEASE TELL ME OR TELL ME WHAT I HAVE TO CHANGE!!! First image: I have to SHOW (DRAWING) the mechanism (with arows and structures of molecules) NOT WORDS PLEASE! of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary Second image: I have to show the mechanism (IMAGE) (with arrows and structures of the molecules) NOT WORDS PLEASE !! for the reaction on the left, where the alcohol A is added fast in one portion HOMEWORK, NOT EXAM!!
