Saponification of ethyl benzoate with caustic soda as alkali gives:

Arrange the products $I$,$II$,$III$ from the following reactions in decreasing order of their acid strength.
$A) \text{Propylbenzene} \xrightarrow[\text{ (ii) } H_3O^{+}]{\text{ (i) } KMnO_4 / OH^{-}} I$
$B) CH_3COOH \xrightarrow[\text{ (ii) } H_2O]{\text{ (i) } Br_2 / \text{red } P} II$
$C) \text{Bromobenzene}$ $\xrightarrow[\substack{\text{ (ii) } CO_2 / \text{dry ether} \\ \text{ (iii) } H_3O^{+}}]{\text{ (i) } Mg / \text{dry ether}} III$

Give the reaction for heating benzoic acid with soda lime,also known as the decarboxylation of benzoic acid.

The correct order of increasing acidic strength among the following is:

Carboxylic acids are easily ionised. What is the main reason for this statement?

Which among the following compounds has the highest boiling point?
