$2-$Hexyne can be converted into $trans-2-$hexene by the action of:

$Ph-C \equiv CH \xrightarrow[MeOH]{MeO^{-}}$ The major product of the reaction is:

An organic compound has a triple bond and no double bond. It can be tested by:

Which of the following would be produced when acetylene reacts with $HCl$?

Identify the alkyne in the following sequence of reactions:
Alkyne $\xrightarrow{\text{H}_2, \text{Lindlar's catalyst}} A$ $\xrightarrow{\text{Ozonolysis}} B \text{ (only)}$
Given that $B$ is obtained from $\text{CH}_2=\text{CH}_2$ via the Wacker process.

$1$-Alkyne and $2$-alkyne can be distinguished by
