1.	Normal water is mainly protium oxide, H_(2)O However, if protium atoms in normal water molecule are replaced completely by deuterium atoms, the resulting water is called heavy water. Acetone exhibits keto-enol tautomerism CH_(3)-overset(O)overset(\|\|)C-CH_(3) hArr CH_(3)-Coverset(OH)overset(\|\|)=(CH_(2)) Which of the following products is chained when acetone is treated with an excess D_(2)O sufficient time in presence of small amount of dilute NaOH solutions ?
Answer» `CH_(3)-overset(OD)overset(\|)C=CH_(2)` `CH_(2)D-overset(OH)overset(\|)C=CH_(2)` `CD_(3)-overset(O)overset(\|\|)C-CD_(3)` `CH_(3)- overset(OH) overset(\|)C=CD_(2)` SOLUTION :
