AC10 Carboxylic acid Flashcards
Do alcohols or carboxylic acids of similar sizes have a higher boiling point
Carboxylic acids
Why do carboxylic acids have a higher boiling point than alcohols of similar size
Because they can both form hydrogen bonds but carboxylic acids also has a permanant dipole
Why does the boiling point of carboxylic acids increase when the size of the carboxylic acid increases
Since there are more electrons and a larger surface area so an increase points of contact so there are more London forces
When naming carboxylic acids, what carbon is carbon one
The carbon bonded to the carboxylic acid group
When reacting a phenol with a carboxylic acid attached, and you add sodium hydroxide / a strong base, what is the product
Where the Na+ is attached to the O- of the OH and the O- of the COOH and H2O is produced
Is the OH acid or carboxylic acid a stronger acid
Carboxylic acid
When adding sodium carbonate/ weak base to a phenol with carboxylic acid attached what is the product
Where Na+ is attached to the COOH but NOT the OH
Why does sodium carbonate only react with the carboxylic acid and not the OH group when added to a phenol with a carboxylic acid
Because COOH is a stronger acid than the OH
What is the name of the CH3OO- ion
Ethanoate
What are the products:
Ethanoic acid + NaOH
CH3COONa + H2O
- Sodium ethanoate + water
What are the products:

What are the products:

Sodium ethanoate + carbon dioxide + water
What are the products:
CH3COOH + metal oxide (NaO)
NaCH3COO + H2O
Sodium ethanoate + water
What are the products:
CH3COOH + NH3
NH4CH3COO
What are the names of the 4 derivatives of carboxylic acids
