CH3-C triple bond CH IN THE P RESENCE OF NANH2 AND CH3-CH2-CL =?
An acid / base reaction. The amide ion acts as a base removing the acidic terminal H to generate the acetylide ion, a carbon nucleophile.
A nucleophilic substitution reaction. The carbanion reacts with the electrophilic carbon in the alkyl halide with loss of the leaving group, forming a new C-C bond.
