Answer:

a Ethanol

that is ethyl alcohol

Answer 2

Answer:

Acetic acid undergoes reduction with $LiAlH_{4}$ to give (a)Ethanol

Explanation:

Acetic acid is a carboxylic acid that contains one acid. Its IUPAC name is ethanoic acid.

Lithium aluminum hydride is a powerful reducing agent, meaning it reduces other substances while also becoming oxidized.

When carboxylic acids are treated with lithium aluminum hydride, the carboxylic acids are reduced to the alcohols that correspond to them.

As a result, acetic acid is converted to ethanol in the presence of this reducing agent.

         $CH_3COOH+LiAlH_3$   →   $CH_3CH_2COOH$

          Acetic acid                         Ethanol

During this reaction, the electrophilic carbon in the polar carboxyl group of acetic acid is added by the nucleophilic H from the anhydride reagent.
