	Rearrangement
		Rearrangements consisting of consecutive 1,2-shifts often take place in a concerted, and therefore stereospecific fashion; however, it must not be assumed that the group shifts are simultaneous.
		Rearrangement to a 2º-carbocation is favored by relief of small-ring strain in the case of pinene, and relief of steric congestion in the case of camphene.
		The rearrangement of acyl nitrenes to isocyanates that is the crux of the Hofmann, Curtius and Lossen rearrangements, is paralleled by the rearrangement of acyl carbenes to ketenes, a transformation called the Wolff rearrangement.

		Rearrangements consisting of consecutive 1,2-shifts often take place in a concerted, and therefore stereospecific fashion; however, it must not be assumed that the group shifts are simultaneous.
		In the Lossen rearrangement (#7) butyl amine adds to the isocyanate to give a substituted urea (urea is NH The Hofmann rearrangement in reaction #8 provides a novel example of the tautomerism of an acetylenic 1°-amine to a nitrile.
		The resulting Wolff rearrangement generates a ketene, which quickly reacts with any hydroxylic or amine reactants that may be present in solution.

		Practically, the rearrangement of a 9,10-ethanoanthracene derivative to 9-formyl-9,10-dihydro-9,10-methanoanthracene has not yet been reported, and it is a new process for the preparation of 9-formyl-9,10-dihydro-9,10-methanoanthracene.

		Part II 1) Give a mechanism for the following rearrangement and explain the role of stereoelectronics in this reaction.
		The following rearrangement can involve high energy intermediates, such as secondary carbocations, if these lead to the formation of very stable intermediates in subsequent steps.
		Another important driving force in rearrangements is the release of ring strain.
