Which of the following arrangements does not represent the correct order of the property stated against it?

Experimentally it was found that a metal oxide has formula ${\text{M}}_{0.98}\text{O}$. Metal $\text{M}$ is present as ${\text{M}}^{2+}$ and ${\text{M}}^{3+}$ in its oxide. Fraction of the metal which exists as ${\text{M}}^{3+}$ would be:

A compound with molecular mass $180$ is acylated with ${\text{CH}}_3\text{COCl}$ to get a compound with molecular mass $390$. The number of amino groups present per molecule of the former compound is:

Given:$E_{{\text{Cr}}^{3+}/\text{Cr}}^0=-0.74\text{V}$$E_{{\text{MnO}}_4^{-}/{\text{Mn}}^{2+}}^0=+1.51\text{V}$$E_{{\text{Cr}}_2{\text{O}}_7^{2-}/{\text{Cr}}^{3+}}^0=+1.33\text{V}$$E_{{\text{Cl}}_2/{\text{Cl}}^{-}}^0=+1.36\text{V}$ Based on the data given above, the strongest oxidising agent will be:

Arrange the following compounds in order of decreasing acidity:Phenol substituted with:
