Stand out and be remembered with Prezi, the secret weapon of great presenters. Creating downloadable prezi, be patient. They should never be used in any other circumstances.

Constrain to simple back and forward steps. Even when wedges are present, only two of the four or five asymmetric ring atoms are situated at the narrow ends of wedges. Send the link below via email or IM Copy.

Incrivelmente absorvente do primeiro ao See more popular or the latest prezis. It is also worth noting that Fischer projections are the only representations of configuration that are not invariant with respect to rotation in estereoquimicaa plane of the paper.

Please log in to add your comment. Because of their simplicity, many well-known angular systems can be represented succinctly using formulas rather than explicit atoms and bonds. T-shaped configurations have three ligands, so they must be clearly differentiated not only from trigonal pyramidal and trigonal planar configurations, but also from tetrahedral configurations that are drawn with an estereoquimicx hydrogen on the central atom.

Stand out and be remembered with Prezi, the secret weapon of great presenters.

Estereoquímica – GRAPHICAL REPRESENTATION OF STEREOCHEMICAL CONFIGURATION

These estereoqui,ica have been used to indicate the position of a hydrogen atom at a ring fusion, with the dot form representing a hydrogen above the plane of the ring and the dash or circle form representing a similar hydrogen below the plane of the ring.

Traditionally, an unlabeled atom represents a carbon atom to organic chemists, but the unlabeled ligands here may represent any sort etereoquimica element or chemical fragment, certainly including a carbon atom, but also potentially a.

Creating downloadable prezi, be patient. They were originally proposed [1,12] for the depiction of carbohydrates, and they remain acceptable for the depiction of carbohydrates and their estereoquimkca [5]. A firewall is blocking access to Prezi content. The configuration of the biaryl system should not solely be represented by solid wedged and hashed wedged bonds to other ring substituents that are distant from the rotatable bond.
