Question

I need help figuring out the answer for this question since my professor does not provide a key for the practice exam, therefore i cannot check my work.

I was doing my professors practice exam for chapter 1 and the first question has me a bit confused about the type of product that would come out of it. Not sure if this would be considered an apoxide ring. I'm submitting an image so you guys can see what I am talking about for part A. For part B i believe the option for the best solvent would be a diethyl ethyl and would like to know if im correct. enter image description here
