Question

acidity of C-H bond in a haloform ​

Answer 1

Explanation:

The C-H bonds on the alpha carbons of ketones are unusually acidic (the pKa of the simplest ketone, 2-propanone, is about 19 in water [Note 2 for ref] a) because the negative charge resulting from deprotonation can be delocalized through resonance to the oxygen atom, which due to its higher electronegativity .
