Experiment 11: dehydration of cyclohexanol theE1 elimination reaction

Rate limiting step of an E1 rxn is?

The carbocation

How do you find theoretical yield?

1. Density=mass/volume 2. Solve for mass of compound given 3. Solve for moles from the mass of the compound given 4. Find the mole ratio of the compounds (the one given and the one not asked for) 5. Solve for the mass of the compound not asked for. 6. The mass of the one not asked for is the answer for theoretical yield.

cyclohexanol undergoes E1 to form..

Cyclohexene

Primary mechanism of this rxn?

E1

Which alcohol will undergo dehydration most readily?

Tertiary alcohol because the carbocations is more stable (3°>2°>1°>methyl)

Phosphoric avid and sulfuric acid are what in this rxn?

catalyst

What is the purpose of this lab?

To synthesize, purify, and analyze the product of an acid dehydration rxn

Which layer is the organic layer?

Top layer
