WM: Acids, Bases, Bonding Flashcards
1
Q
A base is a…
A
Proton acceptor
2
Q
An acid is a…
A
Proton donor
3
Q
Why is a carboxylic acid the most acidic organic acid?
pH 3-4
A
The charge can be spread between two electronegative O atoms = more stable
4
Q
Where does the charge spread when the hydrogen ion dissociates in a phenol?
A
Onto the Benzene ring
5
Q
Why do alcohols have a pH of 7?
A
Because the charge can only spread onto one O atom which is unstable, so the H atom will hardly ever dissociate in water
6
Q
What is acidity?
A
The extent in which the hydrogen atoms dissociate in solution.
Hydrogen in organic acids dissociates partially only
