9. (a) Under certain conditions, the reaction of 0.5 M 1-bromobutane with 1.0 M sodium methoxide forms 1-methoxybutane at a rate of 0.05 mol/L per second. What would be the rate if 0.1 M 1-bromobutane and 2.0 M NaOCH3 were used? (b) Consider the reaction of 1-bromobutane with a large excess of ammonia (NH3). Draw the reactants, the transition state, and the products. Note that the initial product is the salt of an amine (RNH+ Br) which is deprotonated by the excess ammonia to give the amine. (c) Show another SN2 reaction using a different combination of an alkoxide and an alkyl bromide that also produces 1-methoxybutane.

Draw the energy diagram of the following reaction (label and draw reactants, intermediates, and products). Label transition state of the rate limiting step and draw the transition state of the rate determining step. Is it a concerted or stepwise reaction? Write the rate law for this reaction. How do we increase the reaction rate? If we use deutrium-tert-butyl bromide such as (CD3)3CBr instead of (CH3)3CBr, will it increase or decrease the reaction rate? Or there is no meaningful rate change. Write reasons for your answer. Draw mechanisms for reactions by drawing arrows and intermediates.

4) Multistriatin, one of the pheremones of the elm bark beetle, is a volatile compound released by a virgin female beetle when she has found a good food source - an elm tree. Male beetles, which carry the Dutch elm disease fungus, are attracted by the pheromone; the tree becomes infected with the fungus and soon dies. Multistriatin is used to trap the beetles, but the amount in beetles is so miniscule that the compound must be synthesized. The following synthesis of multistriatin uses only chemistry that we have seen in Chem 348. HO. НО Br type O type.
