Tiffany Acevedo · Answer 1

2-methyl-3-hexyn-2-ol can be prepared from Acetylene by treating Acetylene with NaNH ₂ followed by CH ₃ CH ₂ Br, then treating the intermediate with NaNH ₂ followed by acetone and then doing aqueous workup. NaNH ₂ acts as base and abstracts proton from acetylene as the terminal alkynes are acidic in nature. While acetone on reduction gives tertiary alcohol.
