The conversion of a ketone to an aldehyde can be achieved by using a reducing agent such as sodium borohydride (NaBH4) or lithium aluminum hydride (LiAlH4) in a solvent like ethanol or tetrahydrofuran (THF). The reducing agent donates hydride ions to the ketone, breaking the carbon-oxygen double bond and forming an aldehyde.
The conversion of an aldehyde to a ketone can be achieved by using a chemical reaction called the Wolff-Kishner reduction. This reaction involves the use of hydrazine (N2H4) and a strong base, such as potassium hydroxide (KOH), to remove the carbonyl group from the aldehyde, resulting in the formation of a ketone.
The conversion of an aldehyde to an alkyne in organic chemistry is typically achieved through a reaction called the Lindlar catalyst hydrogenation. This process involves using a catalyst made of palladium on calcium carbonate, which selectively reduces the aldehyde group to an alkyne.
To convert an aldehyde to a ketone, one can use a reducing agent such as a metal hydride (e.g. NaBH4) to add a hydrogen atom to the carbonyl group of the aldehyde, resulting in a ketone. This process is known as a reduction reaction.
Benzyl acetate is neither an aldehyde nor a ketone. It is an ester, specifically the ester of benzyl alcohol and acetic acid.
From its structure, we can see that vanillin does not have a ketone functional group, but it has an aldehyde. It also has a phenol and ether functional group. For that reason, I wouldn't categorize is as just an aldehyde.

An aldehyde (as the name says)

They have the same functional group.

Cinnamaldehyde is an aldehyde. Its structure contains an aldehyde functional group (-CHO) attached to a benzene ring.
An aldonization is the formation of an aldol - an aldehyde or ketone with a hydroxy group in the beta- position - usually from a correpsonding aldehyde.
Since it is "dione", it is a ketone, and there should be a comma between the 2 and 3 such as in 2,3-butanedione.
Diacetyl is a ketone. It has a structure with two carbonyl groups attached to a central carbon atom.
Alkyl groups are electron donating (whereas hydrogen atoms aren't). A ketone has 2 alkyl groups attached to the carbonyl carbon, but an aldehyde has only 1 alkyl group attached to its carbonyl carbon. This gives the aldehyde carbon more positive charge character, which makes it a better electrophile than the ketone. Another factor is less stearic hindrence for carbonyl carbon of aldehyde as compare to ketones.
