We are asked to rank the compounds from the strongest acids to weakest.
1. Dicarbonyls have very acidic hydrogens in the middle carbon due to resonance capabilioties. (diketone>ketoester>diester)
2. Single Carbonyls can also resonate which means they can be acidic (Next)
3. Terminal Alkynes can be acidic (Next)
4. Alkanes are the least acidic.
Rank the compounds from strongest acids to weakest. To rank items as equivalent, overlap them.
