The reduction of ethyl ethanoate (ethyl acetate) with lithium aluminum hydride (LiAlH4) results in the formation of ethanol. LiAlH4 is a strong reducing agent that converts the carbonyl group of the ester into a primary alcohol. The reaction involves the nucleophilic attack of the hydride ion on the carbonyl carbon, leading to the cleavage of the ester bond and subsequent protonation to yield ethanol.

How do you prepare alpha napthol?
Alpha-naphthol can be prepared through the reduction of naphthalene using various methods, such as catalytic hydrogenation or using reducing agents like lithium aluminum hydride (LiAlH4). In a typical laboratory synthesis, naphthalene is dissolved in an appropriate solvent, and the reducing agent is added under controlled conditions. The reaction is monitored, and upon completion, the product is purified, often through recrystallization. Safety precautions should be observed due to the toxicity of naphthalene and the reactivity of the reducing agents.

What is the mechanism of the reduction of carboxylic acids using lithium aluminum hydride (LiAlH4)?
When carboxylic acids are reduced using lithium aluminum hydride (LiAlH4), the hydride ion (H-) from LiAlH4 attacks the carbonyl carbon in the carboxylic acid, forming an alkoxide intermediate. This intermediate then undergoes protonation to yield the reduced alcohol product.
How does the lialh4 reduction process convert a functional group into an alcohol?
The LiAlH4 reduction process converts a functional group into an alcohol by adding a hydrogen atom to the functional group, which changes its chemical structure to form an alcohol.
What is the reaction mechanism of carbonyl compounds with LiAlH4, where the effective reducing species is?
The reaction mechanism of carbonyl compounds with LiAlH4 involves the reduction of the carbonyl group to form an alcohol. LiAlH4 acts as the reducing agent in this reaction by donating a hydride ion to the carbonyl carbon, leading to the formation of an alkoxide intermediate which then undergoes protonation to yield the alcohol product.
What is the mechanism of the reduction reaction involving the use of lithium aluminum hydride (LiAlH4) with an aldehyde compound?
