What is a hemiacetal carbon? Hemiacetals: Hemiacetals are an important functional group because they appear in sugars. If a hemiacetal is obtained, then it can easily be hydrolyzed back to the starting componenets. Answer and Explanation:
Molecular FormulaRCH(OH)OR hemiacetal -Introduction Hemiac et al is an organic compound with a specific structure. It is formed by the reaction of the carbonyl carbon of an aldehyde or ketone with the hydrogen atom of an alcohol. Hemiac has the following characteristics: ...

An acetal has two —OR′ groups from the alcohol, an —R group from the original aldehyde, and a hydrogen atom bonded to the original carbonyl carbon. A ketal results from the reaction of a hemiketal with an alcohol in acidic solution. A ketal has two —OR′ groups from the alcohol ...

carbon atom between the carbonyl group and the aromatic ring (C1), electrons of the radical can be more delocalized because of the proximity to the π-system of the aromatic ring, as compared to when the radical forms at the other α-carbon atom (C3). This causes hydroxylation at the C1...
Here, the R groups can be organic fragments (a carbon atom, with arbitrary other atoms attached to that) or hydrogen, while the R' groups must be organic fragments not hydrogen. Hemiacetal A hemiacetal or a hemiketal have the general formula R1R2C(OH)OR, where R1 or R2 is hydrogen or...
