more sp-hybridized carbon, 1,2,3-butatriene has an “extra turn”in its carbon chain, makingthe molecule planar.(b)The planar geometry of the cumulated triene system leads to the situation where cis and transstereoisomers are possible for 2,3,4-hexatriene (CH3CH?C?C?CHCH3). Cis–transstereoisomers are diastereomers of each other.10.35Reaction (a) is an electrophilic addition of bromine to an alkene; the appropriate reagent is brominein carbon tetrachloride.Reaction (b) is an epoxidation of an alkene, for which almost any peroxy acid could be used.Peroxybenzoic acidwas actually used.Reaction (c) is an elimination reaction of a vicinal dibromide to give a conjugated diene and re-
