An aldehyde (as the name says)
Benzaldehyde is an aldehyde. It contains a carbonyl group bonded to at least one hydrogen atom on one side and an aromatic ring on the other side. In contrast, a ketone has a carbonyl group bonded to two carbon atoms.
The functional group of biphenyl is aromatic ring, benzene.
No, benzaldehyde is not an aromatic hydrocarbon. It is an aromatic aldehyde with the chemical formula C6H5CHO. Aromatic hydrocarbons are compounds that contain one or more benzene rings. Benzaldehyde contains a benzene ring but also has a functional aldehyde group, making it an aromatic aldehyde.
Benzaldehyde can undergo auto-oxidation due to the presence of an aldehyde group, which is susceptible to oxidation reactions. The aldehyde group in benzaldehyde can be easily oxidized to form benzoic acid in the presence of air or oxygen.
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.
They have the same functional group.
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.
Cinnamaldehyde is an aldehyde. Its structure contains an aldehyde functional group (-CHO) attached to a benzene ring.
Benzaldehyde has the formula C7H6O, it has the carbonyl carbon of the aldehyde bound to a benzene ring. You can't have a =O unit bound directly to the benzene ring because you would have a carbon with five bonds.
Benzaldehyde is a compound with the chemical formula C7H6O and a distinct almond-like scent. It is commonly used in the production of dyes, perfumes, and flavorings. Benzaldehyde can also be found naturally in certain fruits and nuts.
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.
