Hello everyone, I have been trying to solve this problem but i'm stuck at the reaction with 1-bromo-2 5-dimethoxybenzene and chloroform. I think the first two products (F) and (G) are 2-butene and 2-ethoxibutane from E1 and SN1 reactions with 2-bromobutane.
What do you think?
Thank you for your time.
