In Experiment 13 you will be using a spectrophotometer. Below are some of the steps needed to use the instrument once it is on and warmed up. Organize the steps in the order they must be performed to correctly collect data. A - Measure the absorbance of the solution. B - Adjust absorbance to zero. C - Place colored solution in instrument. D - Set the wavelength on the instrument. E - Place the blank solution in the instrument.

Which one of the following bonds would you expect to be the most polar? a) b–h b) n–h c) p–h d) al–h e) c–h

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
