I am not an organic chemist so I don't know all the answers here but perhaps I can get you pointed in the right direction and you can do the rest.
HC-triplebond-CH + H2O (H2SO4+HgSO4 catalyst)==>CH3CHO (acetaldehyde).
Then the oxidation of CH3CHO produces CH3COOH.
For the acetylene portion, look in your text or notes under reactions of acetylene, particularly hydration. For the oxidation of CH3CHO, look under reactions of aldehydes. Oxidation of aldehydes may be accomplished with KMnO4 or K2Cr2O7, both strong oxidizing agents. I don't know the exact strengths but I suspect that an acid solution is preferred. I hope this helps.
P. S. Let your buddy, who is in your class, in on this. Perhaps the two of you can fill in the missing blanks. I understand the H2SO4, HgSO4 catalyst is quite pertinent to the transition of acetylene to CH3CHO.
OK. I have your answer but you will need to fill in the details.
Propene. Add H2O to form isopropyl alcohol, then oxidize that to produce acetone. The addition of H2O to the double bond is usually done in acid solution. The oxidation to acetone can be accomplished with CrO3 or K2Cr2O7. I hope this gets you started. I found the addition of water under addition reactions of alkenes and the formation of acetone under reactions of alcohols (secondary).
It does help thanks DrBob
Can you help me with another related question?
Write the reaction equation for propene producing acetone
I forgot to mention, but I'm sure you are aware, that CaC2 in water produces the acetylene.
I'll see what I can do about propene to acetone.
Thank you Sir
The chronology of our posts and responses got mixed up a little. The answer to the propene to acetone question is posted before the question.
