Aniline is less basic than ethylamine. This is due to Conjugation of lone pair of nitrogen with the ring The insoluble nature of aniline More Kfc value of aniline Hydrogen bonding 2 / 10 92. Primary amine reacts with carbon disulphide and HgCl2 to produce alkyl isothiocyanate. This reaction is Carbylanine reaction Hoffmann bromamide reaction Perkin reaction Hoffmann mustard oil reaction 3 / 10 93. Nitration of aniline is carried out after acylation because Acylation dectivates the — NH2 group Oxidation can be prevented O-and p-products are obtained in good yield All of these 4 / 10 94.
