Q. Nitroalkane which do not exhibit tautomerism is:

Bihar CECEBihar CECE 2001

Solution:

Key Idea: Tautomerism arises due to presence of labile hydrogen in organic compounds. The compounds having $ \alpha - $ hydrogen show tautomerism.
$\underset{1^{\circ} \text{nitroalkane}}{R- \underset{\overset{|}{H}}{\overset{\underset{|\,\alpha}{H}}{C}}- NO_{2}}\,\,\,\,\, \underset{2^{\circ} \text{nitroalkane}}{R-\underset{\overset{|}{H}}{\overset{\underset{|\, \alpha}{R}}{C}}- NO_{2}} \,\,\,\,\, \underset{3^{\circ} \text{nitroalkane}}{R-\underset{\overset{|}{R}}{\overset{\underset{|\, \alpha}{R}}{R}}- NO_{2} }$
$ \because $ $ {{3}^{o}} $ nitroalkane does not have any $ \alpha -hydrogen $ atom.
$ \because $ $ {{3}^{o}} $ nitroalkane do not show tautomerism
