Practice CBSE Class 12 Amines in the app →Among ammonia, methylamine, aniline, the most basic in aqueous solution is:Acylation of methylamine $CH_3NH_2$ with acetyl chloride $CH_3COCl$ on the lab bench gives:Aniline treated with $NaNO_2/HCl$ at $0-5^\circ$C on the lab bench gives:In the Sandmeyer reaction, benzenediazonium chloride reacts with $CuCl$ on the lab bench to give:Amines are best regarded as derivatives of:The geometry around nitrogen in an amine molecule is:The C to N to E angle in an amine is less than:In the IUPAC system primary amines are named as:Nitro compounds are reduced to amines by hydrogen over:Reduction of nitro compounds with iron scrap uses which acid?Ammonolysis of alkyl halides is carried out in a sealed tube at:The chief drawback of ammonolysis is that it yields a:In ammonolysis the order of reactivity of alkyl halides is:Nitriles reduced with lithium aluminium hydride give:Reduction of a nitrile gives an amine with how many more carbons?Gabriel phthalimide synthesis is used to prepare only:Aromatic primary amines cannot be made by Gabriel synthesis because:Hoffmann bromamide degradation treats an amide with bromine and:The amine from Hoffmann degradation has how many carbons?Lower aliphatic amines are gases carrying a smell that is:Lower aliphatic amines dissolve in water because they form:Which class of amine has no intermolecular hydrogen bonding?The order of boiling points of isomeric amines is:The pKb value of ammonia is:Aromatic amines are weaker bases than ammonia because the aryl group is:Aniline is a resonance hybrid of how many structures?Which reaction is used as a test for primary amines?Hinsberg's reagent used to tell amines apart is:Aniline with bromine water at room temperature gives:The activating power of the amino group is curbed by:Aniline heated with sulphuric acid finally yields:Aniline fails to undergo the Friedel-Crafts reaction because it:Benzenediazonium chloride is made from aniline and nitrous acid at:Replacing the diazo group by chlorine using a copper one salt is the:Introducing halogen using copper powder and a halogen acid is the:Iodobenzene is obtained by treating the diazonium salt with:Coupling of benzenediazonium chloride with phenol gives:
