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

A chemist isolated a compound A with molecular formula C7H13Br. A undergoes very fast SN1 reaction. Spectroscopic evidence indicated that compound A has the following structural characteristics : It contains five sp3-hybridised carbon atoms. Among those five sp3 carbon atoms, three are methyl groups, one CH2 group and one CH group.It also contains two sp2-hybridised carbon atoms. Also there is only one hydrogen atom attached to sp2 carbons.The compound contains a total of six aliylic hydrogen atoms.The carbon atom that holds the Br has one H attached to it.Working SpaceWhen compound A reacts with boiling water, it undergoes a SN1 reaction and produces two principal products B and C. Both B and C are alcohols with their molecular formula C7H14O. Among the two alcohols, B has the OH group attached to a sp3 carbon atom that has no H -atoms bonded to it.Q.If the original compound A is treated with LiAIH4 a new compound D(C7H14) would be produced.
