Chapter 16: Problem 81
Two isomeric alkenes \(\mathrm{A}\) and \(\mathrm{B}\) having molecular formula \(\mathrm{C}_{5} \mathrm{H}_{9} \mathrm{Cl}\) on adding \(\mathrm{H}_{2}\), A gives optically inactive compound, whereas B gives a chiral compound. The two isomers are (1) \(\Lambda\) is 4 -chloro-2-pentene and \(\mathrm{B}\) is 4 -chloro-1 pentene. (2) \(\Lambda\) is 3 -chloro-2-pentene and \(\mathrm{B}\) is 2 -chloro-2 pentene. (3) \(\Lambda\) is 2 -chloro-3-methyl-2-butenc and \(\mathrm{B}\) is 1-chloro-3-methyl-lbutene. (4) \(\Lambda\) is 3 -chloro-1-pentene and \(B\) is 1 -chloro-2 pentene.
