The hydration of propyne results in the formation of:

Which of the following hydrocarbons forms a salt?

Ethyne on reaction with dil. $H_2SO_4$ and $Hg(II)$ gives:

Identify $Z$ in the following series of reaction:
$CH_3-CH_2-OH$ $\xrightarrow[170^{\circ} C]{conc. H_2SO_4} X$ $\xrightarrow[CCl_4]{Br_2} Y$ $\xrightarrow[\Delta]{alc. KOH} Z$

The correct order for acid strength of compounds $CH \equiv CH$,$CH_3 - C \equiv CH$,and $CH_2 = CH_2$ is as follows:

Write the following reactions:
$1$. Complete combustion of ethyne in the presence of air.
$2$. Reaction of propyne with alkaline $KMnO_4$.
