Production of Acetal
Acetal is a functional group in organic chemistry that contains a carbon atom bonded to two -OR groups. It is produced by reacting an alcohol with another compound in the presence of an acid catalyst. The most commonly used alcohol is ethanol, and the acid catalyst is usually dry hydrogen chloride (HCl).
Reaction Mechanism
The reaction mechanism for the production of acetal involves the following steps:
1. Protonation of the alcohol: The acid catalyst (HCl) protonates the alcohol to form an oxonium ion.
2. Nucleophilic attack: The oxonium ion is attacked by the carbonyl group of an aldehyde to form a hemiacetal.
3. Deprotonation: The hemiacetal is deprotonated to form an acetal and a molecule of water.
Reactants and Products
In the production of acetal, the reactants are an alcohol and an aldehyde. The alcohol serves as the nucleophile, while the aldehyde serves as the electrophile. The acid catalyst (HCl) is used to facilitate the reaction.
The product of the reaction is an acetal, which is a stable molecule that is commonly used as a solvent, fuel additive, and plasticizer. Acetal can be further reacted to form more complex molecules, such as acetals and ketals.
Answer
From the above discussion, we can see that the correct option for the question is A, i.e., acetal is produced by reacting alcohol in the presence of dry HCl with acetaldehyde.
