PROYECCIÓN DE FISCHER | Química Orgánica

[Música] muy buenas alumnos a que breaking la de una vez más para hablar de química y en la clase de hoy vamos a estudiar la proyección de fisher recientemente en el canal ya hemos estudiado la proyección de newman habéis visto para que se puede utilizar y de hecho alguno que otro de vosotros me ha preguntado en los comentarios se podría explicar la proyección de fisher así que bueno pues

Introduction to the topic of studying Fisher projection in chemistry.

Understanding Projection Types

• Fisher projection focuses on representing the relative position of multiple atoms in larger molecules, unlike Newman projection which centers on a single carbon-carbon bond.

• Fisher projection allows for analyzing stereochemistry of atoms in complex molecules, offering insights beyond Newman projections used for smaller molecules or specific atom interactions.

para todos aquellos interesados preparamos este vídeo muy bien aquí estamos en frente de la pizarra y antes de empezar voy a explicar para qué se utiliza esta proyección los que hayáis visto el vídeo de la proyección de newman o ya conozcáis de qué va sabréis que se basa en el estudio...

Explanation of the utility and differences between Fisher and Newman projections.

Utility of Projections

• Demonstrates how Fisher projection aids in visualizing complex molecule structures like glucose by showing spatial arrangement of atoms.

Proyección de Fisher

In this section, the speaker explains the projection of Fisher and how to represent molecules using Fischer projections.

Representing Molecules in Fischer Projection

• The molecule has 6 carbon atoms. The aldehyde at the end has changed to acetone at carbon 2.

• Determine the main functional group (carbon 1) for building the molecule using a Fisher projection.

• Start by drawing the main chain with carbon 1 as the functional group on top and the last carbon at the bottom.

• Carbon 2 is not chiral, so it is represented as a flat carbon. Proceed with placing other groups accordingly.

Understanding Stereochemistry

This part focuses on understanding stereochemistry through visualizing molecular structures.

Visualizing Molecular Structures

• Use models or imagination to determine placement of groups around chiral carbons.

• Rotate around each chiral carbon to position hydrogen and other groups correctly in a Fischer projection.

• Repeat the process for all carbons in the molecule to complete the Fischer projection accurately.

Key Tips for Understanding Molecule Structures

The speaker provides tips for mastering molecule structure representations.

Mastering Molecule Structure Representations

• Spatial visualization is crucial for understanding different projections of molecules.

• Knowing how to draw each type of projection enables mental rotation between different representations.
