Does anyone know why nitrogen gets the lone pair instead of oxygen? I thought oxygen was more electronegative.

I understand that the carbonyl group is good to attack, but I'm curious as to why the double bonded electron doesn't go to oxygen (more EN) instead of nitrogenLook closely at the first step.....we have a NUCLEOPHILE. A nucleophile needs to attack an ELECTROPHILE. The carbonyl group is a perfect position. As you can see, the attack allowed the alcohol to add on. This was simply followed by a proton transfer to finish the job. The reaction continues in the same fashion to the opposite side.
I hope this helps.....

If the electrons go from the double bond to O, it would be a single bond and 3 lone pairs right? I'm not sure how that breaks the octet.How could it ? O already has an octet......draw them in to start with, and this should be very very clear. The electrons can move toward the N and maintain the octet.
