Vedclass · Answer

(D) The synthesis of $3$-octyne $(CH_3CH_2C \equiv CCH_2CH_2CH_2CH_3)$ involves the nucleophilic substitution of a bromoalkane with an acetylide ion.The reaction is: $CH_3CH_2C \equiv C^- Na^+ + BrCH_2CH_2CH_2CH_3 \rightarrow CH_3CH_2C \equiv CCH_2CH_2CH_2CH_3 + NaBr$.Here,the alkyne used is $1$-butyne $(CH_3CH_2C \equiv CH)$ and the bromoalkane is $1$-bromobutane ($CH_3CH_2CH_2CH_2Br$ or $BrCH_2CH_2CH_2CH_3$).

$A$ bromoalkane is reacted with the sodium salt of an alkyne to obtain $3$-octyne. What are the bromoalkane and the alkyne respectively?
