For the reaction can someone please synthesize the given products from the given reactants. Multiple reactions/steps will be needed (the arrows designate the minimum number of steps). Also, for the 1st step (reaction) in each synthesis, can you please draw an energy diagram showing the correct number of hills and valleys for that step’s mechanism?

Complete each sentence by matching with the correct statement.Increasing the concentration of a reactant: a. Increases the frequency and energy of molecular collisions which speeds up the rate of the reactionb. Reduces the energy and frequency of the collisions thus slowing down the rate of the reactionc. Increases the frequency of molecular collisions thus speeding up the rate of the reactiond. Increases the activation thus speeding up the rate of the reactione. Lowers the activation energy and speeds up the reactionf. Gives the molecules more energyAdding a catalyst to a reaction:a.

Consider this reaction: Br CH3OH Br-Br H3CO The mechanism proceeds through a first cationic intermediate, intermediate 1. Nucleophilic attack leads to intermediate 2, which goes on to form the final product. In cases that involve a negatively charged nucleophile, the attack of the nucleophile leads directly to the product. H. Br + CH;OH Br Intermediate 2 (product) Intermediate 1 In a similar fashion, draw intermediate 1 and intermediate 2 (final product) for the following reaction. OH + Br2 + HBr Br racemic mixture
