How do you show that ethyne is acidic
WebConsider, for example, the structure of ethyne (common name acetylene), the simplest alkyne. This molecule is linear: all four atoms lie in a straight line. The carbon-carbon triple … WebMar 14, 2024 · I'd suggest that the mercury will first associate with the acetylene forming an Hg- Pi complex which will weaken the triple bond. Then the chloride ion will attack one side of the acetylene and the electron density one of the triple bonds will form a new single bond, first to the mercury ion and then this bond will hydrolyse and pick up a proton.

WebYou make an alkyne by removing HBr, not Br₂. So you first have to add the two hydrogen atoms with H₂/Lindlar. Then, reaction with NaNH₂/NH₃ removes 2 mol of HBr and the terminal H to give CH₃CH₂C≡C:⁻. Further reaction with CH₃Br gives pent-2-yne.
