(a) Carbonyl compounds are at-
tacked by nucleophiles
(b) All aldehyde has a greater partial
positive charge on its carbonyl
carbon
(c) Protonation of a carbonyl com-
pound decreases electrophilic
nature and thus nucleophilic attack
is retarded

Answer 2

Answer:

The incorrect statement., among the following are as under-

Explanation:

(a)The sentence " Carbonyl compounds are attacked by nucleophiles" is-

(a) correct .

The carbonyl group  provides a site for nucleophilic addition or nucleophilic attack and increases the acidity of the hydrogen atoms  which are attached to alpha carbon.

(b) The sentence "All aldehyde has a greater partial positive charge on its carbonyl carbon" is-

(b) correct.

In aldehydes ,the carbonyl carbon generally has more partial positive charge than in ketones as the electron-donating nature of alkyl groups. Aldehydes have only one e- donor group while ketones have two.

(c)The sentence is- "Protonation of a carbonyl com-pound decreases electrophilic nature and thus nucleophilic attack is retarded" is-

(c) correct

Formely, protonation of the carbonyl group at the oxygen takes place because of excess H+ all around. Once protonation has occurred, nucleophilic attack by the nucleophile finishes the addition reaction.

(d) The sentence -"Hydration of CC13CHO is more than that of CH3CHO​" is-

(d) incorrect

This statement is incorrect.
