WebFunctional Groups Stereoisomers (briefly and non-optical only!) Geometric isomers are stereoisomers that are distinct and separate because they cannot freely rotate due to a multiple bond or a ring structure. Geometric isomers are generally not optical isomers unless they also happen to have chiral centers. WebFeb 21, 2024 · All carbon-based (organic) molecules contain functional groups – some more than one of them – and they’re what gives molecules their particular reactivity.

WebOct 1, 2024 · Functional groups are collections of atoms in organic chemistry molecules that contribute to the chemical characteristics of the molecule and participate in predictable reactions. These groups of atoms contain oxygen or nitrogen or sometimes sulfur attached to a hydrocarbon skeleton. WebFeb 28, 2024 · Tables are available in standard spectra manuals that provide ranges of absorbances for specific functional groups. Common groups with characteristic absorbances include aldehydes, ketones, esters, alkenes, alkynes, alcohols, amines, amides, carboxylic acids, nitro groups, and nitriles.

WebMost organic functional groups absorb in the so-called “diagnostic region” of the spectrum at wavenumbers from 1500-4000 cm-1 and can be easily recognized. For example, carbonyl functional groups (C=O) typically show up around 1750 cm -1 and hydroxyl groups (O-H) stretches show up around 3500 cm -1 (see example spectrum below).
