question 5A 2012 practice final

Postby Natalie Yakobian » Tue Mar 08, 2016 5:32 pm

HI,
I am a little lost on question 5A on where the arrows go for step C -> D. Can someone please explain or show me a picture or their work?
Thank you so much!

That reaction step is an intramolecular esterification. An OH- is lost between part C and D. Electrons are distributed to create the cyclic ester.
