Choose the incorrect statement.

Cresols are less acidic than Phenol because electron releasing groups do not favour formation of Phenoxide ion.

Ethanol acts as Nucleophile when the $\mathrm{O}-\mathrm{H}$ bond is broken and acts as Electrophile on getting protonated.

In the acid catalysed hydration of Ethene, an Oxonium ion is formed when it reacts with $\mathrm{H}_3 \mathrm{O}^{+}$and a Carbocation is formed when the Oxonium ion reacts with water.

In the reaction between Ethanol and Conc. $\mathrm{H}_2 \mathrm{SO}_4$ at 413 K , an Oxonium ion is formed when Ethanol gets protonated.
