Lab 22: 4-Methylcyclohexene Abstract: We treated 4-methylcyclohexanol with phosphoric acid‚ and after purification we produced the end product 4-methylcyclohexene. We determined we had a pure product based on the results of the tests with Br2 and KMnO4‚ as well as the IR absorbtion spectrum of the final product. Purpose: The purpose of this experiment is to obtain pure 4-methylcyclohexene by reacting 4-methylcyclohexanol and phosphoric acid. Through distillation

Find the wt% of Ni in the unknown. 7-8) The man in the vat. Once upon a time‚ a workman at a dye factory fell into a vat containing a hot concentrated mixture of sulfuric and nitric acids‚ and he dissolved! Because nobody witnessed the accident‚ it was necessary to prove that he fell in so that the man’s wife could collect his insurance

who killed his family‚ Ames and Darby. After Darby testified‚ Ames was given the death penalty. One would think it would be lethal injection‚ quick and painless‚ Clyde had other plans. He had switched out the usual barbiturate‚ muscle relaxers and potassium chloride and replaced it with more lethal‚ slow acting‚ and more painful poisons. Once this was done‚ he moved onto Darby‚ the one he really wanted to pay. Clyde lures Darby away into a field when Darby grabs Clyde gun but little does Darby know
