1.	The synthesis of higher alkyne from lower alkyne is achieved by adding a bromo alkane in to amixture of Sodium amide and an alkyne. Which of the following combination(s) of bromoalkane and alkyne, can lead to the formation of 3-Octyne.
Answer» 1-bromo pentane and propyne 1-bromo butane and butyne-2 1-bromo butane and butyne-1 1-bromopropane and pentyne-1 Solution :The above REACTION is possible only with terminal (acidic) alkynes. Hence option "B". is not CORRECT as it is non-terminal alkyne
