Medicine: Phenols Flashcards
Definition of phenols
Benzene rings with an alcohol group ( look at notes for drawing )
What does water do to phenols
Dissociates females = behave as a weak acid
H-OH + H2O H-O(minus ) + H3O+ ( oxonium ) ion
Give equation for reaction of an alcohol group and water ( dissociation ) using R
R- OH + H2O R-O(minus ) + H3O+ ( oxonium ) ion
What can and cannot phenols react with
React with anhydrides to form esters
NOT react with carboxylic acid
What do you phenols alcohols and carboxylic acid react differently with
Alkalis and iron (III) chloride
