Hi, please could anyone start me off with the questions below? I'm a bit lost with it to be honest, not even sure what compound E acts as.

Hi, thanks for your response. I think I've managed to figure out all of the displayed structures, but I'm still not sure what compound E would be. Please could you give me a hint on which of the 4 options it is? Thanks.

Also, when it says the most acidic proton, am I correct in saying it's either one of the two H atoms that are bonded to the carbon atom in between the two carbonyl groups, in compound H?

Think about what sort of reagent KOH is and what it might do to the starting compound. 

Please show us the work you have done so far.  This will make it easier for us to help you.

Never mind guys I got it right (checked with my teacher), thanks anyway.
