11. Alkanoic Acids Flashcards
1
Q
What is the functional group in the Alkanoic Acids?
A
The carboxyl group
2
Q
What is vinegar?
A
A dilute solution of ethanoic acid
3
Q
How can ethanoic acid be synthesised?
A
By oxidation of ethanol
4
Q
Why are smaller alkanoic acids miscible (soluble) with water?
A
Because the carboxyl group is polar like the water molecule
Like dissolves like!!
5
Q
Why do alkanoic acids have a pH below 7?
A
Because the carboxyl functional group dissociates in water to produce excess H+ (aq) ions
6
Q
Why do alkanoic acids conduct electricity?
A
Becasue the carboxyl group dissociates into ions. Ionic solutions conduct electricity because ions are free to move.
