In organic chemistry
In organic chemistry, acetylide means the functional group −C≡C−. This group is made by deprotonation of a terminal alkyne, −C≡CH.[1] Alkynes are more acidic than alkanes or alkenes. This means acetylides can be made with strong but common bases like sodium amide.[2]
Safety
Some acetylides (chemical compounds that contain acetylide ions) are explosive.[3][4]
