Classification Tests for Hydroxyl and Carbonyl Containing Compound
CLASSIFICATION TESTS FOR HYDROXYL AND CARBONYL CONTAINING COMPOUNDS
ABSTRACT Hydroxyl- and Carbonyl- containing samples were tasked to be distinguished and classified respectively; the three types of alcohols were to be differentiated along with aldehydes and ketones. Hydroxyl groups are functional groups containing OH- atoms acting as substituents in an organic compound, carbonyl- groups refer to a divalent group consisting of a carbon atom double-bonded to an oxygen atom. Hydroxyl groups are characteristic functional groups of alcohols and phenols, while carbonyl groups are characteristic functional groups of aldehydes and ketones. The samples include ethanol, n-butyl alcohol, sec-butyl alcohol, …show more content…
Aldehydes are organic compounds containing a terminal carbonyl group. This functional group consists of a carbon bonded to a hydrogen atom with a single covalent bond with an oxygen atom with a double bond. Thus the chemical formula for a carbonyl functional group is -CH=O, and the general formula for an aldehyde is R-CH=O.
Ketones features a carbonyl group (C=O) bonded to two other carbon atoms. They differ from aldehydes in a way that carbonyl is placed between two carbons rather than at the terminal end of a carbon structure. They are also distinct from other functional groups, such as carboxylic acids, esters and amines which have a carbonyl group bonded to a hetero atom.
