acid base - Which will be the most acidic hydrogen in the following organic compounds?



Picture 1 and Picture 2


Which will be the most acidic hydrogen in both cases? Please explain.



According to me, in the first compound 2 should be most acidic as in both 1 and 2, resonance occurs but 2’s carbon is closer to the oxygen, which can stabilize the negative charge on carbon.



In the second compound, 1 should be the most acidic as there is $+I$ at 2 by carbon 3, which destabilizes the negative charge on it after removing hydrogen from carbon 2.


Am I correct?
