Nucleophilic PowerPoint Presentations - PPT
ALkanes. Chapter 10.2:. Structure, bonding and chemical reactions involving functional group inter-conversions are key strands in organic chemistry. Chapter 20.1:. Key organic reaction types include nucleophilic substitution, electrophilic addition, electrophilic substitution, and redox reactions. Reaction mechanisms vary and help in understanding the different types of reactions taking place..
8-7. If the carbonyl carbon of an aldehyde or ketone could be attacked by a nucleophilic carbon atom, R:. -. , instead of a hydride ion, both an alcohol and a new carbon-carbon bond would be formed..
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.
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..

The carbonyl group is electrophilic at the carbon atom and hence is. . susceptible to attack by nucleophilic reagents. Thus, the carbonyl group reacts as a . formyl. . cation. or as. . an . acyl .
