Write the products for the following hydrogenation reactions:
(a) <IMAGE>

Verified step by step guidance

Identify the type of reaction: Hydrogenation is the addition of hydrogen (H2) to a molecule, typically involving an alkene or alkyne.

Determine the structure of the reactant: Since the image is not provided, assume a generic alkene structure, such as R-CH=CH-R'.

Understand the mechanism: In hydrogenation, the double bond (\(C=C\)) in the alkene is converted to a single bond (\(C-C\)) by adding hydrogen atoms to each carbon atom involved in the double bond.

Write the product structure: The product will be an alkane, where the double bond is replaced by a single bond, and each carbon atom of the former double bond has an additional hydrogen atom.

Consider the catalyst: Hydrogenation reactions typically require a metal catalyst, such as palladium, platinum, or nickel, to proceed efficiently.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Hydrogenation

Hydrogenation is a chemical reaction that involves the addition of hydrogen (H2) to an unsaturated compound, typically an alkene or alkyne, converting it into a saturated compound. This process is commonly used in organic chemistry to reduce double or triple bonds, resulting in alkanes. Catalysts, such as palladium, platinum, or nickel, are often employed to facilitate the reaction.

Reaction Products

In chemical reactions, the products are the substances formed as a result of the reaction. For hydrogenation reactions, the products are usually saturated hydrocarbons, which can be alkanes. Understanding the structure of the reactants is crucial for predicting the products, as the addition of hydrogen alters the molecular structure and bonding.

Stereochemistry

Stereochemistry refers to the study of the spatial arrangement of atoms in molecules and how this affects their chemical behavior. In hydrogenation reactions, the stereochemistry of the reactants can influence the configuration of the products, particularly in cases where double bonds are involved. Recognizing whether the reaction leads to cis or trans isomers is essential for understanding the outcome of the hydrogenation process.
