(a)
Interpretation:
The structure of the product obtained by the reaction between propene and hydrogen gas in the presence of metal catalyst should be determined.
Concept introduction:
The addition on the alkene is the electrophilic addition reaction. In this reaction, electrophile reacts with carbon-carbon double of the alkene which results in the formation of
The hydrogenation of
A nucleophile is the Lewis base that donates an electron pair to form a covalent bond with the electrophile.
An electrophile is the Lewis acid that accepts the electron to form a bond with the nucleophile.
(b)
Interpretation:
The structure of the product obtained upon heating
Concept introduction:
The preparation of alkene is the type of elimination reaction.
The
The
A nucleophile is the Lewis base that donates an electron pair to form a covalent bond with the electrophile. An electrophile is the Lewis acid that accepts the electron to form a bond with the nucleophile.
The good leaving groups are the weak base. They can be an anion or neutral molecule.

- Lactones, cyclic esters such as compound A, are prepared by halolactonization, an addition reaction to an alkene. For example, iodolactonization of B forms lactone C, a key intermediate in the synthesis of prostaglandin PGF2α (Section 4.15). Draw a stepwise mechanism for this addition reaction.arrow_forwardAlkenes can be converted to alcohols by reaction with mercuric acetate to form a β-hydroxyalkylmercury(II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH4 reduces the C–Hg bond to a C–H bond, forming the alkyl alcohol, a reaction called demercuration. Draw the structures of the Hg-containing compound(s) and the final alcohol product(s) formed in the following reaction sequence, omitting byproducts. If applicable, draw hydrogen at a chirality center and indicate stereochemistry via wedge-and-dash bonds.arrow_forwardPrimary alcohols can react with certain alkenes to give ethers.
