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.
