Nucleophilic - presentation
Substitution Reactions. (Substitution at sp. 3. -hybridized Carbon). Halides are electronegative elements. Thus, in the case of an alkyl halide, R-X the halide atom can leave from carbon, taking the shared pair of electrons with it..
Ch 6- Alkyl Halides Structures and Properties - presentation
Halogen is connected to a tetrahedral carbon. The carbon-halogen bond is polarized with the carbon having a partial positive charge and the halogen having a partial negative charge. The size of the halogen increases as you move down the group.
Retrosynthesis - presentation
Synthetic design involves two distinct steps: . (1) retrosynthetic analysis and . (2) subsequent translation of the analysis into a "forward direction" synthesis. . In the analysis, the chemist recognizes the functional groups in a molecule and disconnects them proximally by methods corresponding to known and reliable reconnection reactions..
