In general as a reaction proceeds, what happens to the rate of the reaction? Select one: a. Generally as a reaction proceeds the reaction rate will increase with time. b. Generally as a reaction proceeds the reaction rate will remain constant with time. c. Generally as a reaction proceeds the reaction rate will decrease with time.
Consider this reaction: Br CH₂OH + Br-Br H₂CO The mechanism proceeds through a first cationic intermediate, intermediate 1. Nucleophilic attack leads to intermediate 2, which goes on to form final product. In cases that involve a negatively charged nucleophile, the attack of the nucleophile leads directly to the product. Year Hot Br + CH₂OH Br Intermediate 1 Intermediate 2 (product) In a similar fashion, draw intermediate 1 and intermediate 2 (final product) for the following reaction. Br H Br₂ + NaBr + H2O H H H NaOH . Pay attention to the reactants, they may differ from the examples. In some reactions, one part of the molecule acts as the nucleophile. Structures are provided for you to modify in the sketchers below. . • You do not have to consider stereochemistry. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate intermediate 1 and intermediate 2 using the symbol from the dropdown menu. Sn [F H On [F I Br -OH HH…
