Acetal vs. Hemiacetal

Acetalnoun

(organic chemistry) Any diether of a geminal diol, R2C(OR')2 (where R' is not H).

Acetalnoun

A limpid, colorless, inflammable liquid from the slow oxidation of alcohol under the influence of platinum black.

Acetalnoun

any organic compound formed by adding alcohol molecules to aldehyde molecules

Acetal

An acetal is a functional group with the connectivity R2C(OR')2). 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.

Hemiacetalnoun

(organic chemistry) Any of a class of compounds of general formula R1R2C(OH)OR' (where R' is not H and R1 or R2 is often hydrogen).

Hemiacetalnoun

an organic compound usually formed as an intermediate product in the preparation of acetals from aldehydes or ketones

Hemiacetal

A hemiacetal or a hemiketal have the general formula R1R2C(OH)OR, where R1 or R2 is hydrogen or an organic substituent. They generally result from the addition of an alcohol to an aldehyde or a ketone, although the latter are sometimes called hemiketals.
