Lab Exam 3 Study Guide
The intermediate species in this reaction is a: - carbocation
The position of the equilibrium can be shifted to favor the products (cyclohexene and
water) by: - Distilling the products from the reaction mixture as they form
Why does cyclohexene have a lower boiling point than cyclohexanol? - Cyclohexene
cannot hydrogen bond; cyclohexanol can
The reaction is called a dehydration reaction because - Water is produced by
removing H and OH from the reactant
6.00 g (0.0600 mol) of cyclohexanol is dehydrated to produce 3.20 g of cyclohexene
(C6H10, 82.0 g/mol) What is the theoretical yield of the reaction? - 4.92 g
6.00 g (0.0600 mol) of cyclohexanol is dehydrated to produce 3.20 g of cyclohexene
(C6H10, 82.0 g/mol) What is the percent yield of this reaction? - 65.0 %
The rate law for the SN1 reaction is - rate = k[(CH3)CCl)]
What is the intermediate species in this reaction? - t-butyl carbocation
If the number of moles of reactant is doubled and the volume of the reaction solvent
is doubled, what effect would that have on the reaction rate? - No effect on the
reaction rate
What does one measure when doing a kinetics experiment? - The concentration of
whatever compound (reactant or product) that is most readily measured
