Predict the product of the following reaction

I am asking for help with my organic chemistry assignment. I have the most trouble with predicting the products of reactions and the mechanisms of those reactions. I know it is a little hard to read, so I will type the questions out.1. a)Predict the product of the following reaction.b) Provide an arrow pushing mechanism for the reaction above that accounts for the formation of the product. Explicitly include all non-bonding electrons and charges.2. Fill in the missing reactant or product with the appropriate stereochemistry. If there are multiple possible products, indicate the major product.3. a) Rank the starting materials below according to the relative rate at which they will undergo the following substitution reaction. (1=fastest, 3=slowest)b) Rank the following reactions according to their relative rate. (1=fastest, 4=slowest)4. Provide a three-step synthetic sequence for the preparation of the following products from the indicated organic starting materials. Your answers should include intermediate compounds as well as the reaction conditions for each step.If you could just guide me a little on how to start these, I would really appreciate it!
