How many hydrogen atoms are replaced by D in the following tautomeriza

1.	How many hydrogen atoms are replaced by D in the following tautomerization? CH_(3)-overset(Ph)overset(\|)C=underset(Ph)underset(\|)C-overset(O)overset(\|\|)C-CH_(3)underset(D_(2)O)overset(D^(o+))rarr
Answer» Solution :H-atoms which are PRESENT in conjugation with `-overset(O)overset(\|\|)C-` are replaced by D. `CH_(3)-overset(CH_(3))overset(\|)C=underset(CMe_(3))CH_(3) underset(D_(2)O"Longtime")overset(D^(+))rarrCD_(3)-overset(CMe_(3))overset(\|)C=underset(CMe_(3))underset(\|)C-CD_(3)`
