Lithium aluminum hydride (LiAlH4) reduces carboxylic acids by donating a hydride ion (H-) to the carbonyl carbon of the carboxylic acid, resulting in the formation of an alcohol. This reaction is a common method for converting carboxylic acids to alcohols in organic chemistry.
What else can I help you with?
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 can lithium aluminum hydride (LiAlH4) reduce?
Lithium aluminum hydride (LiAlH4) can reduce a variety of functional groups in organic chemistry, such as carbonyl compounds (aldehydes, ketones, carboxylic acids, esters), epoxides, and nitriles.
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.
Does LiAlH4 reduce ketones?
Yes, LiAlH4 (lithium aluminum hydride) is a strong reducing agent that can reduce ketones to form secondary alcohols.

How would propanoic acid be converted into propanol?
Propanoic acid can be converted to propanol through reduction. One common method involves using a reducing agent like lithium aluminum hydride (LiAlH4) in an appropriate solvent to chemically reduce the carboxylic acid functional group to an alcohol.
What is the formula of the hydride formed by sulfur?
A hydride is hydrogen anion (a negative ion), written as H- A few examples of hydrides are Sodium hydride, NaH Calcium hydride, CaH2 Sodium borohydride, NaBH4 Lithium aluminum hydride, LiAlH4
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.
Can LiAlH4 reduce carboxylic acids?
Yes, LiAlH4 can reduce carboxylic acids to alcohols.
What role does LiAlH4 play in a chemical reaction?
LiAlH4, also known as lithium aluminum hydride, is a powerful reducing agent commonly used in organic chemistry. It plays a crucial role in chemical reactions by donating hydride ions to reduce functional groups such as carbonyl compounds, allowing for the formation of new bonds and the synthesis of various organic compounds.
How does the reduction of carboxylic acid with LiAlH4 affect the overall reaction mechanism?
The reduction of carboxylic acid with LiAlH4 changes the overall reaction mechanism by converting the carboxylic acid functional group into an alcohol functional group. This reduction process involves the transfer of hydride ions from LiAlH4 to the carbonyl carbon of the carboxylic acid, leading to the formation of an aldehyde intermediate which is further reduced to an alcohol. This change in functional groups alters the chemical properties and reactivity of the compound.
