Under suitable conditions, 2-bromohexane reacts with sodium hydroxide to produce a mixture of five organic products, A, B, C, D, and E.
Products A, B, and C are alkenes:
Products D and E are alcohols:
Give the names of the two concurrent mechanisms responsible for the formation of the alkenes and the alcohols.
Define the term stereoisomers.
Deduce the IUPAC name of isomer A. Explain why A does not exhibit stereoisomerism.
Outline the mechanism for the reaction of 2-bromohexane with sodium hydroxide to form alkene A.
Deduce the IUPAC name of isomer B and the name of isomer C. Explain the origin of the stereoisomerism in B and C.
Draw 3D representations of enantiomers D and E to show how their structures are related.
A student compares the rates of hydrolysis of 1-chlorohexane, 1-bromohexane, and 1-iodohexane. State and explain the order in which precipitates appear when these halogenoalkanes are reacted with aqueous silver nitrate.
