Carboxyllic acid: 1) Functional group? 2) They are? |
1) R-COOH. 2) Weak acids (only partially dissociate in solution). |
|
When they dissociate they form: |
A carboxylate ion, the double bond in this will dissociate giving the carboxylate a strong polarity, thus attracting the hydrogen back. |
|
Increasing alkyl groups: |
Increases the polarity as these push electron density towards the negative region. |
|
Adding a halogen: |
Decreases the polarity as this withdraws electron density from the delocalised region. |
|
The solubility of carboxylic acids: |
Depends on the chain length. – Long chain = insoluble – Short chain = soluble |
