Two new bonds are created when a ketone and HCN react. C-OH bonds are created when the H from HCN adds to 0 in C=O, and C-CN bonds are created when -CN adds to C. Both options A and C provide the ketone, but option A contains the one with the same number of carbon atoms as the product. The resulting substance is known as “cyanohydrin” and contains both a CN and an OH group on the same carbon.

Due to both steric and electronic effects, aldehydes are typically more reactive than ketones toward nucleophilic substitutions. Aldehydes have a larger R group attached to one side of the carbonyl group and a relatively small hydrogen atom attached to the other. However, in ketones, the carbonyl group has R groups bonded to both sides. As a result, aldehydes have less steric hindrance than ketones.

Ketones have two electron-supplying groups attached to the carbonyl carbon, whereas aldehydes only have one R group to provide electrons toward the partially positive carbonyl carbon. The partial positive charge on this atom decreases and its nucleus becomes weaker as more electrons are added to the carbonyl carbon.

A compound with white crystals is created when an impure carbonyl compound is combined with a saturated solution of sodium hydrogen sulfite, also known as sodium bisulfite. For this reason, carbonyl compounds are separated from non-carbonyl compounds using sodium bisulphite.

Aldehydes have a -CHO group as their functional group. One pi bond is formed between the O atom and the C atom in the -CHO group. As a result, carbon will hybridize as sp2.

Hydrazones are compounds with a hydrazone group (-C=N-NH-) that are created when aldehydes react with hydrazine (NH2-NH2).

Benedict’s solution tests are used to identify reducing agents that convert copper citrate (blue solution) to “copper(I)oxide or cuprous oxide (red precipitate)”, so option C is accurate.

The presence of acid or alkali causes any nucleophilic reaction to occur. For instance, we use diluted HCl and NaCN to create a nitrile from an aldehyde. We also use alkali and aqueous iodine in the iodoform reaction. Therefore, in nucleophilic addition reactions, both acid and alkali/base are employed.

Primary alcohols can be oxidized to produce aldehydes. Aldehydes are the initial product of the oxidation of primary alcohols. Carboxylic acids are produced when aldehydes undergo additional oxidation. Option D is therefore the right choice.

Aldol is produced along with a water molecule through a condensation reaction. Aldol condensation is the term used to describe the reaction of two similar carbonyl compounds to produce an aldol product. It is referred to as crossed aldol condensation when the condensation reaction takes place between two distinct carbonyl compounds.
