Vedclass · Answer

(D) The synthesis of $3$-octyne $(CH_3CH_2C \equiv CCH_2CH_2CH_2CH_3)$ involves the alkylation of an acetylide ion.First,the terminal alkyne reacts with sodium amide $(NaNH_2)$ to form a sodium acetylide:$CH_3CH_2C \equiv CH + NaNH_2 \rightarrow CH_3CH_2C \equiv C^- Na^+ + NH_3$Then,the acetylide ion acts as a nucleophile and attacks the bromoalkane $(CH_3CH_2CH_2CH_2Br)$ via an $S_N2$ mechanism:$CH_3CH_2C \equiv C^- Na^+ + BrCH_2CH_2CH_2CH_3 \rightarrow CH_3CH_2C \equiv CCH_2CH_2CH_2CH_3 + NaBr$Thus,the reactants are $1$-bromobutane $(CH_3CH_2CH_2CH_2Br)$ and $1$-butyne $(CH_3CH_2C \equiv CH)$.

The synthesis of $3$-octyne is achieved by adding a mixture of sodium amide and an alkyne to a bromoalkane. What are these bromoalkane and alkyne?
