# Which of the following statement is FALSE?

## $$A) Carboxylic acids are mildly acid (pKa’s ~ 5) B) Carboxylic acids are lower boiling points than alcohols of similar molecular weights because they form hydrogen-bonded dimmers. C) Electron –donating groups decrease the acidity of carboxylic acids. D) Carboxyl salts are produced when carboxylic acids are treated with NaOH

Answer = $b$

#### Explanation:

Boiling points of carboxylic acids are generally higher than that of the corresponding alcohols. Let's see, boiling point of methanol, $338 K$, ethanol, $352 K$, propanol, $370 K$; methanoic acid, $374 K$, ethanoic acid, $391 K$, propanoic acid, $414 K$. So why are the boiling points of the acids higher? (I am doing this in Kelvin because I can't remember how to get the degree sign!).
