The products of the given reaction including the sequence of steps are to be determined. Concept introduction: ▸ Dehydrogenation is a reaction in which the hydrogens are removed from an organic molecule using various reagents. It is the reverse of hydrogenation. ▸ The hydroboration-oxidation reaction is a two-step organic reaction that converts an alkene , an unsaturated hydrocarbon into alcohol via the addition of water across the double bond. The hydrogen and hydroxyl group are attached in syn addition that leads to cis stereochemistry.

Question

Show how the following ethers might be synthesized using (1) alkoxymercuration–demercuration and (2) the Williamson synthesis. (When one of these methods cannot beused for the given ether, point out why it will not work.)(a) 2-methoxybutane (b) ethyl cyclohexyl ether

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
