|
How does the reactivity of phenol compare to benzene in electrophilic substitution reactions?
phenol and benzene have similar reactivity
phenol is less reactive than benzene
phenol is more reactive than benzene
|
Which of the following contributes to phenol's increased reactivity compared to benzene?
the electron-donating -OH group activates the aromatic ring
the lone pair of electrons on the oxygen atom is not involved in the aromatic π system
the electron-donating -OH group deactivates the aromatic ring
the -OH group reduces the electron density within the ring
|
What happens when phenol is treated with bromine water?
bromine water is decolourised, and 2,4,6-tribromophenol precipitates
bromine water turns orange, and 2,4,6-tribromophenol precipitates
bromine water turns orange, and 2,4-diibromophenol precipitates
bromine water is decolourised, and 2,4-diibromophenol precipitates

Why does phenol not react with sodium carbonate (Na2CO3) solution?
phenol is a relatively weak acid
sodium carbonate is a weak base
sodium carbonate is insoluble in water
phenol is a strong acid
