Number of hydrogen replaced by Deuterium in the given reaction are :
D₂O/DO⁻, Prolonged
Options:
Answer:
D
Solution:
The compound is 3-methylcyclohex-2-en-1-ol - an allylic alcohol, not an enol : the OH sits on an sp3 carbon and there is no C=O or C=C-OH unit that could tautomerise. The only exchangeable hydrogen is the O-H proton itself, which swaps instantly with D₂O. Hence only 1 hydrogen is replaced.
