When one hydrogen atom in \(NH_3 (ammonia) \)is replaced by an alkyl group, it forms an amine. Amines are compounds derived from ammonia with one or more hydrogen atoms replaced by alkyl or aryl groups.
Which of the following amines does not give foul smell of isocyanide on heating with chloroform and ethanolic KOH ?
Amines are usually formed from amides, imides, halides, nitro compounds, etc. They exhibit hydrogen bonding which influences their physical properties. In alkyl amines, a combination of electron releasing, steric and H-bonding factors influence the stability of the substituted ammonium cations in protic polar solvents and thus affect the basic nature of amines. Alkyl amines are found to be stronger bases than ammonia. Amines being basic in nature, react with acids to form salts. Aryldiazonium salts, undergo replacement of the diazonium group with a variety of nucleophiles to produce aryl halides, cyanides, phenols and arenes.
