?
Which is the position will the incoming substitute be attached to with an electron-withdrawing group?
Position 3
1 of 6
The difference between the nitration of arenes and phenols
Reagent: arenes: concentrated nitric acid and sulfuric acid. phenol: dilute nitric acid. condition: arenes: 50-60 celius. phenols: lower temperature
2 of 6
Why can't phenol undergo esterification by heating with concentrated sulfuric acid?
phenol is not nucleophilic enough because of the delocalization of electron over the ring
3 of 6
State a method to identify phenol
Add orange bromine water to the phenols. Phenols can be determined when white precipitate is observed. (2,4,6-tribromophenol)
4 of 6
Condition of esterification of phenol
Add acyl chloride and base(NaOH).
5 of 6
Why is the melting point of phenol relatively high?
Strong hydrogen bonds.
