1.	In carbonyl compounds, the carbonyl group is polar as well as in sp^(2) hybridisation state. As a result, these compounds are highly reactive in nature and takepart in the addition reactions. The mechanism of these reactions is nucleophilic in nature and is catalyseed in the weakly acidic medium. The extent of nycleophilic addition is influenced by two factors. These are steric effect of the groups attached to the carbonyl carbon atom. Both tend to decrease the reactivity of these compounds in the nuclephilic addition reactions. Important properties of carbon compounds are : nucleophilic addition and acidity of alpha-hydrogen atoms. , Which factor is most useful in explaning these two ?
Answer» PRESENCE of carbon-oxygen double bond. Resonance in carbonyl group. Ability of oxygen to ACCOMMODATE negative charge. All are EQUALLY important. Solution :Both typesof REATION are possible because of electron withdrawing NATURE of carbonyl grorp. As a result , oxygen atom acquires a negative charge.
