In the reduction of ethyl ethanoate with LiAlH4 the product obtained is?
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.
What is the nomenclature for ch3-ch2-ch2-ch2-ch2-ch2-ch2-cho?
The compound CH3-CH2-CH2-CH2-CH2-CH2-CHO is an aldehyde with a straight-chain structure. It consists of a seven-carbon chain (heptanal) with an aldehyde functional group (-CHO) at one end. Therefore, the correct IUPAC name for this compound is heptanal.
What are complex hydrides?
Complex metal hydrides are hydrides containing in the molecule two cations - as LiAlH4.
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.
Compound A C11H12O which gave a negative Tollens test was treated with LiAlH4 followed by dilute acid to give compound B which could be resolved into enantiomers.?
Compound A (C11H12O) likely contains a ketone or an aromatic compound, as it gives a negative Tollens test, indicating it is not an aldehyde. Treatment with LiAlH4 suggests that it is being reduced, likely to an alcohol or another functional group. The fact that compound B can be resolved into enantiomers indicates that it possesses a chiral center, which may have been introduced during the reduction process or through structural rearrangement. Thus, compound A is likely a ketone or similar structure that, after reduction, forms a chiral alcohol or derivative.
Is lialh4 a reducing agent?
Yes, LiAlH4 is a reducing agent.
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.
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.
Can LiAlH4 reduce carboxylic acids?
Yes, LiAlH4 can reduce carboxylic acids to alcohols.
In the reduction of ethyl ethanoate with LiAlH4 the product obtained is?

Does LiAlH4 reduce ketones?
Yes, LiAlH4 (lithium aluminum hydride) is a strong reducing agent that can reduce ketones to form secondary alcohols.
What is the mechanism of the reduction reaction involving the use of lithium aluminum hydride (LiAlH4) with an aldehyde compound?
In the reduction reaction using lithium aluminum hydride (LiAlH4) with an aldehyde compound, the mechanism involves the transfer of a hydride ion from LiAlH4 to the carbonyl carbon of the aldehyde, resulting in the formation of an alcohol. This process is known as nucleophilic addition.
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.
