In a reaction of aniline, a coloured product C was obtained.

Which one of the following on reduction with lithium aluminium hydride yield a secondary amine?

• Nitroethane

• Methylisocyanide

• Acetamide

• Acetamide

Which of the following is more basic than aniline?

• Diphenylamine

• Triphenylamine

• p-nitroaniline

• p-nitroaniline

The correct increasing order of basic strength for the following compounds is 

• II < III < I 

• III < I < II

• III < II < I

• III < II < I

Which of the following reactions is appropriate for converting acetamide to methanamine?

• Carbylamine reaction

• Hoffmann hypobromamide reaction

• Stephens reaction

• Stephens reaction

The correct order of N-compounds in its decreasing order of oxidation states is

• HNO₃, NH₄Cl, NO, N₂

• HNO₃, NO,NH₄Cl, N₂

• HNO₃, NO, N₂, NH₄Cl

• NH₄Cl, N₂, NO, HNO₃

Which of the following compounds can form a zwitter ion?

• Aniline

• Acetanilide

• Glycine

• Benzoic acid

Nitration of aniline in strong acidic medium also gives m-nitroaniline because

• Inspite of substituents nitro group always goes to only m-position.

• In electrophilic substitution reactions amino group is meta directive.

• In acidic (strong) medium aniline is present as anilinium ion.

• In absence of substituents nitro group always goes to m-position.

Which of the following carbocations is expected to be most stable?
