The acryl group is one of the functional groups sorted in the chemical class of acryl where one of four hydrogen atoms in ethene is replaced with a different functional group. Compounds containing an acryl group can be referred to as "acrylic compounds". The word acryl as prefix instead of vinyl as noun is used when the substituting functional group is particular one. For example, vinyl group bonding with nitrile group is called acrylonitrile but not vinyl nitrile, adding -onitrile after acryl- for the name of the acryl compounds. Also, carboxyl groups of acrylic acid can react with ammonia adding -amide after acryl- for the name of the acryl compounds like acrylamide or alcohol adding -ate after acryl- for the name of the acryl compounds like acrylate. Note: when group name whose head letter is consonant follows, the variant form of acrylo- precedes it meanwhile the original term acryl- precedes vowel letter. In organic chemistry functional groups are specific groups of atoms within molecules, that are responsible for the characteristic chemical reactions of those molecules. ...

In chemistry, a carboxyl group is a functional group consisting of a carbon atom doubly bonded to an oxygen atom and single-bonded to a hydroxyl (-OH) group, typically written as -COOH: where R is a hydrogen or an organic group. ... Acrylic acid or prop-2-enoic acid is a chemical compound with the formula C3H4O2 and structure (which is sometimes abbreviated as CH2=CHCOOH). ...

In general usage, alcohol (from Arabic al-kukhūl الكحول = the spirit, the chemical.) refers almost always to ethanol, also known as grain alcohol, and often to any beverage that contains ethanol (see alcoholic beverage). ... Acrylate monomers are esters that contain vinyl groups, that is, two carbon atoms double bonded to each other, directly attached to the carbonyl carbon. ...
