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
