How will you prepare the following ?
(i) 10 -Hexyne from ethyne
(i) Ethanol from ethyne
(ii) 3-Hexanone from 3-hexyne.
(i) To prepare 1-hexyne from ethyne, you can follow these steps:
1. Start with ethyne (C2H2).
2. React ethyne with 1,2-dibromoethane (CH2Br-CH2Br) in the presence of alcoholic KOH (potassium hydroxide).
3. The reaction is an anti-Markovnikov addition of HBr to ethyne, resulting in the formation of 1,2-dibromoethane.
4. Then, treat 1,2-dibromoethane with alcoholic KOH. It will
