Carboxyllic Acids Flashcards
1
Q
What does a COOH consist off ?
A
Carbonyl and a hydroxyl
2
Q
why are carboxylic acids soluble?
A
they can form H bonds with water molecules
3
Q
what type of acids are carboxylic acids and what do they do in water?
A
they are weak acids which only partially dissociate in water
(releases H+ ion)
4
Q
write an equation for when carboxylic acid reacts with a metal
A
carboxylic acid + metal = carboxylate salt + hydrogen
2CH3CH2COOH + Ca –> (CH3CH2COO-)2Ca2+ + H2
5
Q
Write an equation for the reaction of a carboxylic acid and a metal oxide
A
COOH + metal oxide –> carboxylate salt + H2O
6
Q
How do you test for a carboxylic acid and give the equation
A
- add a carbonate e.g Na2CO3
- effervescence
- 2CH3CH2COOH (aq) + Na2CO3 –> 2CH3CH2COO- Na+ + CO2 + H2O
