This carbanion can be used as a C centered nucleophile. For each type of carbanion shown, the nature of the hybrid orbital containingthe electron pair is important.
Overview of Pka Of Alkyne An unsaturated hydrocarbon that has a triple bond between two carbon atoms is called alkynes. A simple type of alkyne that has a triple bond but there is no functional group will make a homologous series. It has a chemical formula of CnH2n
