The correct acidity order of phenol $(I)$,$4-$hydroxybenzaldehyde $(II)$ and $3-$hydroxybenzaldehyde $(III)$ is:

Identify the product formed in the reaction.
Phenol $+$ conc. $H_2SO_4$ $\xrightarrow{373 \ K}$ product

The conversion of $O$-acylated phenol in the presence of $AlCl_3$ to $C$-acylated phenol is an example of which type of organic reaction?

The major product of the following reaction is
$2-(2-hydroxyethyl)phenol$ $\xrightarrow[2. \, CH_3I \, (1. \, eq.)]{1. \, K_2CO_3}$

Suppose the following reaction:
Benzene $(C_6H_6) + CH_3-CH=CH_2$ $\xrightarrow{H^{\oplus}} A$ $\xrightarrow{O_2} B$ $\xrightarrow{H^{\oplus} / \Delta} C + CH_3-CO-CH_3$
The structure of intermediate compound $B$ will be

The major reason that phenol is a better Bronsted acid than cyclohexanol is that
