The structure of products of given reaction should be drawn. Concept Introduction: Terminal alkynes are unusual for simple hydrocarbons in that they can be deprotonated using an appropriate base (typically N a N H 2 ) to generate a carbanion. The acetylide carbanion is a good nucleophile and can undergo nucleophilic substitution reactions (usually S N 2) with 1 o or 2 o alkyl halides ( C l , B r o r I ) which have electrophilic to produce an internal alkyne. 3 o alkyl halides are more likely to undergo elimination. One or both of the terminal H atoms in ethylene H − C ≡ C − H can be substituted providing access to monosubstituted and symmetrical or unsymmetrical (R not equal to R') substituted alkynes R − C ≡ C − R ' . The product is also an alkyne, The S N 2 reaction is a type of reaction mechanism in which one bond is broken and one bond is formed i.e., in one step. S N 2 is a kind of nucleophilic substitution reaction mechanism.
