What is an example of a nucleophilic addition reaction?
- When this reaction takes place, it is an example of a nucleophilic addition reaction In theory the reduction of a carboxylic acid is a two stage process, from the carboxylic acid to the aldehyde and then further reduction from the aldehyde to the primary alcohol.
What is electrophilic and nucleophilic substitution?
- Electrophilic and nucleophilic substitution: The electrophilic substitution reaction involves the displacement of a functional group by an electrophile. Mostly, hydrogen atoms are displaced by this reaction. Such reactions are found in both aromatic and aliphatic compounds.
Why does the Order of reactivities of carbonyl compounds increase in nucleophilic addition reactions?
- The electron density at the carbonyl carbon increases with the increase in the +I effect. As a result, the chances of attack by a nucleophile decrease. Hence, the increasing order of the reactivities of the given carbonyl compounds in nucleophilic addition reactions is:
What is S N 2 (nucleophilic substitution bimolecular) reaction?
- (b) S N 2 ( Nucleophilic substitution bimolecular) reaction is a single step process e.g., 3. Elimination Reactions In these reactions, two groups from the same or adjacent atoms are lost and electron deficient or unsaturated compound is formed. These can be of two types :
