Among the following, the most acidic compound is :

A hydrocarbon $\mathrm{X}$ with molecular formula ${\mathrm{C}}_4{\mathrm{H}}_6$ decolorizes bromine water and forms a white  precipitate in ethanolic ${\mathrm{AgNO}}_3$ solution Treatment of $\mathrm{X}$ with ${\mathrm{HgCl}}_2$ in aqueous ${\mathrm{H}}_2{\mathrm{SO}}_4$ produces a compound, which gives a yellow precipitate when treated with ${\mathrm{I}}_2$ and $\mathrm{NaOH}$. The structure of $\mathrm{X}$ is :

The major product of the following reaction is

The structure of $3$-methylpent-$2$-ene is

 In the reaction of $1 -$bromo$-3-$chlorocyclobutane with two equivalents of sodium in ether, the major product is

The reaction of an alkene $\mathrm{X}$ with bromine produces a compound $\mathrm{Y}$, Which has $22.22\%\mathrm{C}, 3.71\%\mathrm{H}, 74.07\%\mathrm{Br}$. The ozonolysis of alkene $\mathrm{X}$ gives only one product. The alkene $\mathrm{X}$ is [Given : atomic mass of $\mathrm{C}=12; \mathrm{H}=1; \mathrm{Br}=80$]

In the following reaction

$\mathrm{X}$ and $\mathrm{Y}$, respectively, are

An organic compound X with molecular formula ${\mathrm{C}}_6{\mathrm{H}}_{10},$ when treated with $\mathrm{HBr},$  forms a gem dibromide. The compound X upon warming with ${\mathrm{HgSO}}_4$ and dil. ${\mathrm{H}}_2{\mathrm{SO}}_4,$  produces a ketone, which gives a positive iodoform test. The compound X is
