Question

A. Name at least two experimental parameters that can affect the determination of the boiling point when performing a distillation. State how to optimize those two parameters so that you can get the correct boiling point. The solvent used can affect the rates of SN1 reactions.

B.What common protic solvents are used for these types of reactions? Explain why the rates of SN1 reactions are faster in polar, protic solvents than in polar, aprotic solvents.

C. Using structural formulas and arrows to show electron movement, write the mechanism for the reaction of t-butyl alcohol with HCl to produce t-butyl chloride.

Answer 1

A) EXPERIMENTAL PARAMETERS THAT CAN AFFECT DETERMINATION OF BOILING POINT ARE

1) THE BAROMETRIC PRESSURE- WE NEED TO MAKE SURE THE ATMOSPHERIC PRESSURE IS CLOSE TO THE NORMAL PRESSURE WHICH IS 760 mm of Hg.

2) THE EXPERIMENTAL APPARATUS SHOULD NOT HAVE ANY LEAKAGE OTHERWISE WE WILL NOT GET THE EXACT TEMPERATURE.
