Why is this? The simplest explanation is that there is a direct connection between C − H acidity and the amount of s character associated with the σ -bonding carbon orbital. atacama desert wikipediaWebTerminal alkynes are much more acidic than most other hydrocarbons. Removal of the proton leads to the formation of an acetylide anion, RC = C: -. The origin of the enhanced acidity can be attributed to the stability of the acetylide anion, which has the unpaired electrons in an sp hybridized orbital. atacama drilling ltda
