1. Which reaction below occurs faster through an SN2 mechanism and why? Draw the transition states of each reaction to explain your answer. OH to bomto Br OH b) OH 2. The reaction of 9.0 g of 1-butanol (MW = 76g/mol) with 13.0 g of sodium bromide (MW = 103 g/mol) with excess acid produces 8.5 g of 1-bromobutane (MW 137 g/mol). a. What is the purpose of the acid? b. What is the % yield for the reaction? Show...

In our experiment we will use three different substrates: 1°,
n-butyl chloride; 2°, sec-butyl chloride; and 3°, tert- butyl
chloride, and we will evaluate their reactivity and the rate of the
reaction in an SN1 reaction. We will use an acid-base indicator to
monitor the completion of the reaction and a salt, silver nitrate,
to obtain a precipitate. The success of the reaction is evidenced
by the change in color of the indicator (from orange to red) due to
the...

We saw in this experiment that an ester group with the carbonyl carbon attached to the benzene ring serves as a meta-director, resulting in methyl Meta-nitrobenzoate as the major product of the reaction. Given that a methoxy (-OCH_3) group attached to the benzene ring serves as an orthopara director, draw the major products of the reaction shown below. Use your pre-lab lecture notes to answer this question. Explain using the resonance structures (referred to as the "sigma complex") why the...

I need help with my pre and post lab questions.
The three compounds below were spotted on a TLC plate and developed to give the TLC plate shown. Which compound corresponds to which spot? Calculate the Rf value for spot B in the TLC plate shown above. When using polarity to determine the relative rates at which organic compounds travel up the TLC plate, we are considering compounds of similar molecular weight. It should also be noted that Rf values...
