WebPhenol is considered as a weak acid and NaOH is a strong base. Hence, this reaction is considered as an acid-base reaction or also known as a neutralization reaction. We know … WebMar 18, 2024 · The mechanism of the reaction between phenol, sodium hydroxide and carbon dioxide. Welcome to the Highschool Help Forum! The forum is currently in "Beta" …
WebMar 5, 2016 · The mechanism of this reaction is that $\ce {NaOH}$ being a strong base with some extreme conditions abstracts H from C adjacent to C containing Cl while Cl also leaves. This creates benzyne as an intermediate. Subsequent addition of $\ce {NaOH}$ forms the phenoxide ion.
