Which of the following compounds can form a zwitter ion?
Aniline
Acetanilide
Glycine
Benzoic acid
C.
Glycine
Amphoteric Nature of Glycine: In aqueous solution, glycine exists as an inner salt or a dipolar ion.
This doubly charged ion is known as a Zwitterion or an ampholyte. Due to formation of the ampholyte, glycine acts both as an acid or a base.
In aqueous solution, Zwitter- ion tends to lose a proton. Hence, if electrolyzed, the negative glycine ion will migrate to anode.
The pH value for the isoelectric point of glycine is 6.0.
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.
