Isomerie in der organischen Chemie

In der organischen Chemie begegnen dir oft Verbindungen, die zwar die gleiche Summenformel besitzen, deren Stoffeigenschaften sich aber teils dramatisch unterscheiden. Dieser auf den ersten Blick merkwürdige Sachverhalt lässt sich mit einem Blick auf die molekulare Struktur der Stoffe klären: Bei sogenannten Isomeren sind die Atome unterschiedlich miteinander verknüpft, die Bindungsverhältnisse unterscheiden sich voneinander.

Wofür ist das wichtig?

The shape of molecules is super important to life as we know it. In this episode of Crash Course Organic Chemistry we’re learning about stereochemistry and how to identify molecules as chiral or achiral. And as always, we’ll be doing a lot of practice!

Enantiomers have almost all the same chemical and physical properties, so it can be tough to separate them. But it’s still super important that we know how to tell them apart! In this episode of Crash Course Organic Chemistry, we’ll recap all the types of isomers we’ve learned about so far, and also learn about polarimetry as a way to separate enantiomers and how to predict the number of stereoisomers a molecule will have.

note_alt

Arbeitsblatt

Chirale ("händische") Moleküle zeichnen sich dadurch aus, dass sie sich nicht mit ihrem Spiegelbild zur Deckung bringen lassen (so wie die rechte und die linke Hand). Das ist dann der Fall, wenn sie mindestens ein asymmetrisches C-Atom (also eines, das vier echt verschiedene Substituenten besitzt) aufweisen und keine Spiegelachse besitzen ("Meso-Verbindung"). Wässrige Lösungen von Stoffen mit chiralen Moleküle sind i.d.R. optisch aktiv .

Cover: Molekülbaukasten zum Selbstbauen

In vielen Bereichen der Chemie hilft es, Verbindungen im dreidimensionalen zu betrachten. Vor allem in der Stereochemie spielt die dreidimensionale Darstellung eine große Rolle, da die zweidimensionale Darstellung vieles nicht gut darstellen kann. Um ein besseres Verständnis vom räumlichen Bau zu bekommen helfen Molekülbaukästen. Diese kannst du erstaunlich einfach selbst nachbauen!

Isomerie einfach erklärt – Definition & Formen – Konstitutionsisomerie, Stereoisomerie, Konformationsisomerie und Konfigurationsisomerie – Organische Chemie. Unter Isomerie versteht man mehrere Verbindungen, die die gleiche Summenformel und Molekülmasse haben. Man unterscheidet dabei zwischen Konstitutionsisomerie und Stereoisomerie. Die Stereoisomerie wird weiter in Konfigurationsisomerie und Konformationsisomerie unterteilt. Die Konfigurationsisomerie weiter in Enantiomerie und Diastereomerie. Bei der Konstitutionsisomerie besitzen mindestens 2 Moleküle die gleiche Summenformel, die Verknüpfung der Atome ist jedoch unterschiedlich. Bei der Stereoisomerie besitzen ebenfalls mindestens zwei Moleküle die gleiche Summenformel, die Verknüpfung der Atome befindet sich jedoch an derselben Stelle.

Cover: More Stereochemical Relationships: Crash Course Organic Chemistry
videocam

Video

Enantiomers have almost all the same chemical and physical properties, so it can be tough to separate them. But it’s still super important that we know how to tell them apart! In this episode of Crash Course Organic Chemistry, we’ll recap all the types of isomers we’ve learned about so far, and also learn about polarimetry as a way to separate enantiomers and how to predict the number of stereoisomers a molecule will have.

Arbeitsblatt

Chirale (“händische”) Moleküle zeichnen sich dadurch aus, dass sie sich nicht mit ihrem Spiegelbild zur Deckung bringen lassen (so wie die rechte und die linke Hand). Das ist dann der Fall, wenn sie mindestens ein asymmetrisches C-Atom (also eines, das vier echt verschiedene Substituenten besitzt) aufweisen und keine Spiegelachse besitzen (“Meso-Verbindung”). Wässrige Lösungen von Stoffen mit chiralen Moleküle sind i.d.R. optisch aktiv .
