Question

NaNH2 followed by acetone and an aqueous workup, then NaNH2 followed by CH3CH2Br. NaNH2 followed by CH3CH2Br, then NaNH2 followed by CH3C(OH)BrCH3. H2, Lindlar followed by KMnO4 (cold, dilute), then a heated mixture of bromoethane and 2-bromopropane. NaNH2 followed by CH3CH2Br, then NaNH2 followed by 2-bromopropene, and finally catalytic H2SO4 in water. NaNH2 followed by CH3CH2Br, then NaNH2 followed by acetone and an aqueous workup. Choose the right reagent or series of reagents from the ones listed below to prepare 2-methyl-3-hexyn-2-ol from acetylene. NaNH2 followed by acetone and an aqueous workup, then NaNH2 followed by CH3CH2Br. NaNH2 followed by CH3CH2Br, then NaNH2 followed by CH3C(OH)BrCH3. H2, Lindlar followed by KMnO4 (cold, dilute), then a heated mixture of bromoethane and 2-bromopropane. NaNH2 followed by CH3CH2Br, then NaNH2 followed by 2-bromopropene, and finally catalytic H2SO4 in water. NaNH2 followed by CH3CH2Br, then NaNH2 followed by acetone and an aqueous workup.
