The addition of a hydride ion (H^-) and a proton (H⁺) results in the reduction of a carbonyl group. The elimination of H^- and H⁺ from an alcohol results in the formation of a carbonyl group. For the following reaction:

Identify the atom of the carbonyl where the hydride ion is added. Explain.

True or False: The alcohol CH₃CH₂C(CH₃)(OH)CH₂CH₃ can be formed when an aldehyde or ketone undergoes a reduction reaction. Justify your answer.

Draw the alcohol product of the given reaction using a condensed structural formula:

reduction of propionaldehyde by hydrogen in the presence of a platinum catalyst

Give the line-angle formula of the alcohol formed when the molecule below is reduced using hydrogen and a nickel catalyst.
