Concept Introduction:
Addition of H2gas to a multiple bond is known as hydrogenation. In the presence of palladium metal as the catalyst H2 molecules react with
Answer to Problem 76P
Explanation of Solution
When an aldehyde reacts with H2 gas in the presence of palladium metalresulting product is an alcohol of the initial aldehyde molecule. Palladium metal act as a catalyst to the reaction that provides a surface to bind both the H2 and carbonyl compound which reduce the activation energy of the reaction.
Hydrogen atoms in the alcohol molecule shown below, which are indicated in red color are the added H during the hydrogenation reaction.

Concept Introduction:
In the presence of alcohol in the acidic medium, aldehydes undergo addition reactions and give acetal in two steps.
Hydrogen atom and CH3 groups in the acetal and hemiacetal molecules shown below, which are indicated in red color are the added molecules during the reaction.
Answer to Problem 76P
Explanation of Solution
In the presence of alcohol in the acidic medium, aldehydes undergo addition reactions and give acetal in two steps. In the first step aldehydes form hemiacetals and during the second step it converts to an acetal molecule of the respective aldehyde molecule.
Addition of one molecule of alcohol in to an aldehyde forms a hemiacetal, one bond of the

Concept Introduction:
In the presence of waterandacid, acetals undergo hydrolysis reaction and produce aldehydes.
OR' groups in the acetal molecule shown below, which are indicated in red color are the molecules which becomes alcohol molecules during the hydrolysis.
Answer to Problem 76P
Explanation of Solution
Acetals are stable molecules, but their bonds can cleave by a reaction with water and produce aldehydes.
In the acetal molecule, two bonds of the
CH2CH3 groups in the acetal molecule shown below, which are indicated in red color are the molecules which becomes alcohol molecules during the hydrolysis.
