What are the reactions of carbonyl group?
- Chapter 23. Carbonyl Condensation Reactions As a result of the large dipole of the carbonyl group: 1. The carbonyl carbon is electrophilic and is the site of addition reactions by nucleophiles; 2. The ?-protons are acidic and can be deprotonated by strong bases to give an enolate, which are nucleophiles and react with electrophiles.
What happens when a carbonyl reactant is treated with water?
- If a carbonyl reactant composed of 16 O (colored blue above) is treated with water incorporating the 18 O isotope (colored red above), a rapid exchange of the oxygen isotope occurs. This can only be explained by the addition-elimination mechanism shown here. 1. Reversible Addition Reactions
How do less basic reagents react with the carbonyl group?
- These less basic reagents can react with the carbonyl group via two pathways: nucleophilic addition-protonation and electrophilic addition-protonation. Under neutral or basic conditions, nucleophilic attack of the electrophilic carbon takes place.
How to identify the presence of a carbonyl group in a compound?
- There are a number of tests that can be used to identify the presence of a carbonyl group in a compound. These rely on the oxidising nature of the various carbonyl compounds. This reagent is prepared by warming a mixture of ammonia (aq) and silver nitrate (aq) to give ammoniacal silver(I) ions, [Ag(NH 3) 2] +.
