Current Question (ID: 10865)

Question:

$\text{Which of the following organic compounds exhibit tautomerism?}$

Options:

1. $\text{I and II}$
2. $\text{I, III and IV}$
3. $\text{I, II and IV}$ (Correct)
4. $\text{I, II, III and IV}$

Solution:

$\text{Hint: For tautomerism aldehyde or ketone must have } \alpha \text{ hydrogen.}$ $\text{Compounds 1, 2, and 4 will show tautomerization but the third will not show.}$ $\text{The third compound did not contain alpha hydrogen, that why it will not show tautomerization. Hence, option third is the correct answer.}$ $\text{The tautomerism structures are as follows:}$ $\text{Compound I: Phenyl vinyl alcohol } \rightleftharpoons \text{ Phenylacetaldehyde}$ $\text{Compound II: 1,3,5-cyclohexanetrione } \rightleftharpoons \text{ 1,3,5-trihydroxybenzene (phloroglucinol)}$ $\text{Compound III: para-benzoquinone (does not show tautomerism due to lack of } \alpha \text{-hydrogen)}$ $\text{Compound IV: 1,2-cyclohexanedione } \rightleftharpoons \text{ 1,2-dihydroxybenzene (catechol)}$ $\text{Therefore, compounds I, II, and IV exhibit tautomerism.}$
