Which of the following statements is not correct?a)Aldehydes and keton...

Explanation:

Aldehydes and ketones undergo nucleophilic addition:
- Aldehydes and ketones have a carbonyl group, which is a carbon atom double-bonded to an oxygen atom. This makes the carbon atom electrophilic and susceptible to nucleophilic attack.
- Nucleophilic addition reactions involve the addition of a nucleophile to the carbonyl carbon, resulting in the formation of a new compound.

Aldehydes and ketones undergo electrophilic substitution:
- This statement is not correct. Aldehydes and ketones typically undergo nucleophilic addition reactions, not electrophilic substitution reactions. Electrophilic substitution reactions are more commonly observed in aromatic compounds, such as benzene derivatives.

Lower members of aldehydes and ketones are soluble in water due to hydrogen bonding:
- Aldehydes and ketones with lower molecular weights are soluble in water due to the presence of hydrogen bonding between the carbonyl group and water molecules. This allows for interactions that enhance solubility.

Aldehydes and ketones contain polar carbonyl group:
- Aldehydes and ketones contain a polar carbonyl group, which consists of a carbon atom double-bonded to an oxygen atom. This polarity is responsible for many of the chemical properties exhibited by aldehydes and ketones.

Read the passage given below and answer the following questions:Reductive alkylation is the term applied to the process of introducing alkyl groups into ammonia or a primary or secondary amine by means of an aldehyde or ketone in the presence of a reducing agent. The present discussion is limited to those reductive alkylations in which the reducing agent is hydrogen and a catalyst or "nascent" hydrogen, usually from a metalacid combination; most of these reductive alkylations have been carried out with hydrogen and a catalyst. The principal variation excluded is that in which the reducing agent is formic acid or one of its derivatives; this modification is known as the Leuckart reaction. The process of reductive alkylation of ammonia consists in the addition of ammonia to a carbonyl compound and reduction of the addition compound or its dehydration product. The reaction usually is carried out in ethanol solution when the reduction is to be effected catalytically:Since the primary amine is formed in the presence of the aldehyde it may react in the same way as ammonia, yielding an additional compound, a Schiff's base (RCH= NCH2R) and finally, a secondary amine. Similarly, the primary amine may react with the imine, forming an addition product which also is reduced to a secondary amine Finally, the secondary amine may react with either the aldehyde or the imine to give products which are reduced to tertiary amines.Similar reactions may occur when the carbonyl compound employed is a ketone.Q. The reaction of ammonia and its derivatives with aldehydes is called
