Complete each hydrogenation reaction. b.

검증된 단계별 안내

Identify the double bond in the given molecule. In this case, the double bond is between the two carbon atoms in the cyclohexene ring.

Understand that hydrogenation involves the addition of hydrogen (H2) across the double bond, converting it into a single bond.

Add one hydrogen atom to each of the carbon atoms that were originally involved in the double bond.

Redraw the molecule with the new single bond and the added hydrogen atoms. Ensure that the rest of the molecule remains unchanged.

Verify that the resulting molecule is fully saturated, meaning there are no more double or triple bonds present.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Hydrogenation

Hydrogenation is a chemical reaction that involves the addition of hydrogen (H2) to an unsaturated compound, typically an alkene or alkyne, resulting in the formation of a saturated compound. This process is commonly used in organic chemistry to convert double or triple bonds into single bonds, thereby increasing the hydrogen content of the molecule.

Alkenes and Alkynes

Alkenes are hydrocarbons that contain at least one carbon-carbon double bond, while alkynes contain at least one carbon-carbon triple bond. These unsaturated hydrocarbons are more reactive than their saturated counterparts (alkanes) due to the presence of these multiple bonds, making them key targets for hydrogenation reactions to produce alkanes.

Catalysts in Hydrogenation

Hydrogenation reactions often require a catalyst to proceed efficiently, typically a metal such as palladium, platinum, or nickel. These catalysts facilitate the breaking of the H-H bond in molecular hydrogen and help to align the reactants for effective bonding, thus lowering the activation energy and increasing the reaction rate.
