Question

p-Nitrophenol is a stronger acid than phenol while p-cresol is a weaker acid. This can be explained as (A) — CH3 group decreases the electron density on oxygen of O — H group making p-cresol a weaker acid (B) — NO2 group decreases electron density on oxygen of O — H group making p-nitrophenol a stronger acid (C) — CH3 group increases the electron density on oxygen of O — H group making release of H+ easier (D) — NO2 group increases the electron density on oxygen of O — H group making release of H+ easier

Tardigrade Admin · Accepted Answer

Correct answer is (b) — NO2 group decreases electron density on oxygen of O — H group making p-nitrophenol a stronger acid

Q. $p$ -Nitrophenol is a stronger acid than phenol while $p$ -cresol is a weaker acid. This can be explained as

$— C H_{3}$ group decreases the electron density on oxygen of $O — H$ group making p-cresol a weaker acid

$— N O_{2}$ group decreases electron density on oxygen of $O — H$ group making $p$ -nitrophenol a stronger acid

$— C H_{3}$ group increases the electron density on oxygen of O $— H$ group making release of $H^{+}$ easier

$— N O_{2}$ group increases the electron density on oxygen of $O — H$ group making release of $H^{+}$ easier

Correct answer is (b) $— N O_{2}$ group decreases electron density on oxygen of $O — H$ group making $p$ -nitrophenol a stronger acid

Q. p-Nitrophenol is a stronger acid than phenol while p-cresol is a weaker acid. This can be explained as

—CH3​ group decreases the electron density on oxygen of O—H group making p-cresol a weaker acid

—NO2​ group decreases electron density on oxygen of O—H group making p-nitrophenol a stronger acid

—CH3​ group increases the electron density on oxygen of O —H group making release of H+ easier

—NO2​ group increases the electron density on oxygen of O—H group making release of H+ easier
