N ow that we're familiar with the structure and preparation of alkenes, let's look at their chemical reactions. The characteristic reaction of alkenes is addition to the double bond according to the general equation:

ADDITION TO THE CARBONYL GROUP Idehydes and ketones contain an acyl group RC-bonded either to hydrogen or to another carbon

SOLUTIONS TO TEXT PROBLEMS 3.1 (b) The sawhorse formula contains four carbon atoms in an unbranched chain. The compound is butane, CH:CH,CH, CH3 CH3 HH H-H CH ()Rewrite the structure to show its constitution. The compound is

10.1 As noted in the sample solution to part(a), a pair of electrons is moved from the double bond toward the positively charged carbon

assuming that there is no resonance stabilization in 1, 3,5-cycloheptatriene, we predict that its heat of hydrogenation will be three times that of cycloheptene or 330/mol (78.9 kcal/mol)

SOLUTIONS TO TEXT PROBLEMS 15.1 The two primary alcohols, 1-butanol and 2-methyl-1-propanol, can be prepared by hydrogenation of the corresponding aldehydes

Oxirane 2-(Chloromethyl)oxirane This compound is more commonly known as epichlorohydrin. (c)Epoxides may be named by adding the prefix epoxy to the IUPAC name of a parent compound specifying by number both atoms to which the oxygen is attached

ENOLS AND ENOLATES SOLUTIONS TO TEXT PROBLEMS 18.1(b) There are no a-hydrogen- atoms in2,2-dimethylpropa, because the a-carbon- atom bears three methyl groups
