		Both static reactor and shock-tube measurements of the Arrhenius parameters for the thermal isomerization of methylcyclopropane in the temperature range 695—1154 K are reported in B. Kalra, J. Cho, and D. Lewis, J.
		Cyclopropane is added to all reactant mixtures and the observed rate constant for the conversion to propene is used to calculate reaction temperature with the well-established Arrhenius parameters for the isomerization: E
		GC peak heights indicate that the extent of the total conversion of methylcyclopropane to 1-butene, cis-2-butene, trans-2-butene, and 2-methylpropene are in the ratios 1.00 : 0.60 : 0.54 : 0.28.

		Methylcyclopropane Isomerization Kinetics at 990 – 1154 K
		The structural isomerization of methylcyclopropane to its products 1-butene, 2-methylpropene, cis-but-2-ene and trans-but-2-ene was studied using a single-pulse shock tube.
		The present values for cis- and trans-but-2-ene are now equal within experimental uncertainties, and are consistent with the formation of the same biradical intermediate.

		Title : Kinetics of Solid State Chain Reactions Abstract : In this project in the Physical Chemistry Program of the Chemistry Division, Professor Wight of the University of Utah will measure the rates of solid-state chain reactions in low temperature matrices in real time using FTIR spectroscopy.
		Chlorine atom-hydrocarbon chain reactions involving ethylene or methylcyclopropane will be initiated by laser photolysis and monitored as a function of temperature and relative concentration of reagents.
		These reactions are initiated by ultraviolet laser photolysis of thin solid films formed by vapor deposition of the reagents at cryogenic temperatures (10-100 K).

		(5 points) Starting from methylcyclopropane, write names and structures for all the different monochlorination products that would be expected from free radical chlorination with Cl2 and light.
		Indicate the ones that would be chiral, and indicate whether they would be expected to be racemic or not.
		The rate should depend only on the concentration of RBr and not on RO-.

		Click on the image for a video of the interconversions of the two chair conformations of cyclohexane.
		If we replace any of the six hydrogen atoms of cyclopropane with a methyl group, we obtain methylcyclopropane (click here for the rules for
		With dimethylcyclopropane, we can place the second methyl group on the same carbon atom as the first and obtain 1,1-dimethylcyclopropane, or we can place it on one of the adjacent carbon atoms and obtain 1,2-dimethylcyclopropane.

		You should be familiar with the following aromatic rings and heterocycles (IUPAC names in bold):
		These structures are treated as parent compounds when connected to simple substituents (e.g., methylbenzene, methylcyclopropane), but are named as modifiers when high-priority functionality is contained on another chain.
		You should also be aware of special cases when these substituents are connected directly to an acid functionality:
