Answer:
Ketone
Explanation:
Element = α-hydrogen
The base (OH-) ion removes one of the α-hydrogen atom that is some what acidic. The atom is removed from the aldehyde and ketones to form a carbanion or the enolate ion. Due to the reasonance stabilization of enolate anion, there is acidity present in the α-hydrogen.
Thus, after the deprotonation process the negative charge will be in conjugation with the pi orbital of the formed carbonyl, In this case the base will prefer to abstract alpha hydrogen from a ketone. Therefore, a strong base can abstract an α-hydrogen from Ketone.
