Relevant wiki: Grignard Reagent
Product E is a Secondary ( 2 ) Alkoxide ( 1 ) Thus the answer is 2 1 Note: Product D is a grignard reagent and product B is an epoxide. When mixed, the grignard will favor attacking the least substituted carbon in the epoxide ring. For this reason, product E will open up to form a secondary alkoxide.
