(b)Write out the structure in detail, and identify the longest continuous chain that includes thedouble bond.The longest chain contains six carbon atoms, and the double bond is between C-3 and C-4.The compound is named as a derivative of 3-hexene. There are ethyl substituents at C-3 andC-4. The complete name is 3,4-diethyl-3-hexene.(c)Write out the structure completely.The longest carbon chain contains four carbons. Number the chain so as to give the lowestnumbers to the doubly bonded carbons, and list the substituents in alphabetical order. Thiscompound is 1,1-dichloro-3,3-dimethyl-1-butene.(d)The longest chain has five carbon atoms, the double bond is at C-1, and there are two methylsubstituents. The compound is 4,4-dimethyl-1-pentene.(e)We number this trimethylcyclobutene derivative so as to provide the lowest number for thesubstituent at the first point of difference. We therefore number
