Orientation in organic chemistry
WitrynaFor organic molecules with multiple double bonds, it is sometimes necessary to indicate the alkene location for each E or Z symbol. For example, the chemical name of alitretinoin is (2 E ,4 E ,6 Z ,8 E )-3,7-dimethyl-9-(2,6,6-trimethyl-1-cyclohexenyl)nona-2,4,6,8-tetraenoic acid, indicating that the alkenes starting at positions 2, 4, and 8 are ...

Orientation in organic chemistry
Did you know?
When the substituent groups are oriented in the same direction, the diastereomer is referred to as cis, whereas, when the substituents are oriented in opposing directions, the diastereomer is referred to as trans. An example of a small hydrocarbon displaying cis–trans isomerism is but-2-ene. Alicyclic compounds can also display cis–trans isomerism. As an example of … Witryna23 sty 2024 · Organic compounds, molecules created around a chain of carbon atom (more commonly known as carbon backbone), …
Witryna21 lut 2024 · Few, if any, other problems in organic chemistry have received so much attention over so many years, and there are now sufficient data on the orientation and reactivity effects of ring substituents in electrophilic substitution to permit the formation of some very valuable generalizations. WitrynaThe first thing to recognize is that the proportions of ortho, meta and para substitution in a given case reflect the relative rates of substitution at each of these sites. If we use the nitration of benzene as a reference, we can assign the rate of reaction at one of the carbons to be 1.0.

The following example shows how a proton acid HY can add to the π-bond of an unsymmetrical alkene with either Markovnikov or anti-Markovnikov orientation, depending on the reaction conditions used.
