Definition of the noun acetal
What does acetal mean as a name of something?
noun - plural: acetals
- any organic compound formed by adding alcohol molecules to aldehyde molecules
Alternative definition of the noun acetal
- [organic chemistry] Any diether of a geminal diol, R2C(OR')2 (where R' does not = H).
Acetal: An acetal is a functional group with the following connectivity R₂C₂, where both R' groups are organic fragments. The central carbon atom has four bonds to it, and is therefore saturated and has tetrahedral geometry. The two R'O groups may be equivalent to each other or not. The two R groups can be equivalent to each other or not, and one or both can even be hydrogen atoms rather than organic fragments. Acetals are formed from and convertible to carbonyl compounds. The term ketal is sometimes used to identify structures associated with ketones rather than aldehydes, and historically, the term acetal was used specifically for the aldehyde cases. Cellulose is a ubiquitous example of an acetal.
