The correct order of acidity of the following compounds is:

An organic compound having molecular formula ${\mathrm{C}}_2{\mathrm{H}}_6\mathrm{O}$ undergoes oxidation with ${\mathrm{K}}_2{\mathrm{Cr}}_2{\mathrm{O}}_7/{\mathrm{H}}_2{\mathrm{SO}}_4$ to produce $\mathrm{X}$ which contains $40\%$ carbon, $6.7\%$hydrogen and $53.3\%$ oxygen. The molecular formula of the compound $\mathrm{X}$ is

Among formic acid, acetic acid, propanoic acid and phenol, the strongest acid in water is:

The stability of carbanions,

$\begin{array}{cccc}{\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{CH}}_2\stackrel{⊝}{\mathrm{C}}{\mathrm{H}}_2& {\mathrm{CH}}_3\stackrel{⊝}{\mathrm{C}}{\mathrm{HCH}}_2{\mathrm{CH}}_3& {\left({\mathrm{CH}}_3\right)}_3\stackrel{⊝}{\mathrm{C}}& {\mathrm{CH}}_3\stackrel{⊝}{\mathrm{C}}\left(\mathrm{Ph}\right){\mathrm{CH}}_2{\mathrm{CH}}_3\\ \mathrm{I}& \mathrm{II}& \mathrm{III}& \mathrm{IV}\end{array}$
follows the order:

The order of basicity of

in water is:
