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] +.
