Hello People,

Ok I am stuck on the following question. Please help:

I know that the acidic hydrogens are the one which are next to the carbonyl carbon. we have most acidic and then we have weak acidic, then how does it apply to this question?
Can someone please teach me how to do this question?
Thank you guys.

Think about why H adjacent to C=O is relatively acidic. Look up resonance and delocalisation. The most acidic H will be one that produces the most stable anion on deprotonation.
