Q. $(A)C_{2}H_{5}NH_{2}\underset{(ii)AgNO_{2}}{\overset{(i)NOCl}{\rightarrow}}\lbrack W\rbrack$ $(B)\left( CH_{3} \right)_{2}CHNH_{2}\underset{(ii)AgNO_{2}}{\overset{(i)NOCl}{\rightarrow}}\lbrack X\rbrack$ $(C)\left( CH_{3} \right)_{3}\ CNH_{2}\underset{(ii)AgNO_{2}}{\overset{(i)NOCl}{\rightarrow}}\lbrack Y\rbrack$ $(D)CH_{3}CH\left( NH_{2} \right)C_{2}H_{5}\underset{(ii)AgNO_{2}}{\overset{(i)NOCl}{\rightarrow}}\lbrack Z\rbrack$ Which product will not show tautomerism?
A) $W$
B) $X$
C) $Y$
D) $Z$
Explanation
(c)
Presence of $\alpha$-H atom is the main condition for exhibiting tautomerism.
The reactant taken in reaction ($C$) does not contain any $\alpha$-H atom, thus the product $(Y)$will also show the absence of $\alpha$-H atom, Hence, $Y$ will show tautomerism
