1) Predict the major product for the following reaction. (LDA is a strong base) 1. LDA H 2. نم H LDA 3. H20
The epoxide below, when reacted with a catalytic amount of strong base, undergoes a polymerization reaction Applying what you know about the mechanism of epoxidering opening by strong nucleophiles write tout, choose the correct structure of the polymer NaOH (cat.) Алл Ллл ОН h ОН ОН улл Онон ОН но но \ НО > A Moving to another question will save this response.
what is the major product of this reaction and why?
ignore what is already written. thanks!

Draw the missing major organic product(s), starting
material(s), or reagents for each of the following reactions (DO
NOT WRITE +EN AS A PRODUCT (ie draw everything out!)! And remember
stereo and regiochemistry.) Assume reagents are in excess unless
otherwise indicated. **To make things simple, I indicated what is
needed for each section! Please don't just put the answers, but
explanations as well on why. Thanks!
