All of the above statements are true regarding the boiling point trends of amines.

The main product of the reaction between an amine and a carbonyl compound is an amide.

The main product of the reaction between an amine and a haloalkane is a quaternary ammonium salt.

The product of the reaction between ammonia and an alkyl halide is an amine.

The reaction of ammonia with an alkyl halide primarily forms a primary amine.

The reaction of ammonia with an alkyl halide initially forms a primary amine.

CH3NH2 (methylamine) and C2H5NH2 (ethylamine) exhibit structural isomerism as they have different carbon skeletons.

Dimethylamine is a secondary amine as it has two alkyl groups attached to the nitrogen atom.

Nitrobenzene can be reduced to aniline using reducing agents like Sn/HCl.

Nitrous acid can be used to distinguish between primary, secondary, and tertiary amines, as it reacts differently with each type.

Trimethylamine is a tertiary amine as it has three alkyl groups attached to the nitrogen atom.

Aniline is an aromatic amine as it contains a benzene ring attached to the amine group.

N(CH3)3 (trimethylamine) is a tertiary amine as it has three alkyl groups attached to the nitrogen.

Primary amines can be prepared from alkyl halides through nucleophilic substitution reactions with ammonia.

An acid chloride is used to convert an amine to an amide through acylation.
