What is the defining functional group of alkanoic acids?
The carboxyl functional group (-COOH)
What is the general formula for alkanoic acids?
R-COOH
What does the "R" in the general formula R-COOH represent?
An alkyl group (a hydrocarbon chain)
What is the simplest alkanoic acid?
Methanoic acid (HCOOH)
What is the root name for an alkanoic acid with 3 carbon atoms?
Propanoic
What suffix is added to the root name of alkanoic acids?
-oic acid
How does the structure of alkanoic acids contribute to their acidic properties?
The carboxyl group (-COOH) allows them to donate protons (H+) in aqueous solutions
How do you determine the full name of an alkanoic acid?
By combining the root name based on the number of carbon atoms with the suffix "-oic acid"
What is the correct name for the alkanoic acid with the formula CH3(CH2)2COOH?
Butanoic acid
Why do alkanoic acids have relatively high boiling points?
Due to strong intermolecular hydrogen bonding
What type of acids are alkanoic acids classified as?
Weak acids
What happens during acid-base reactions involving alkanoic acids?
They donate protons (H+) to bases, forming salts
What is formed when alkanoic acids react with alcohols?
Esters
What are the key physical properties of alkanoic acids?
- Polarity due to the carboxyl group
- Relatively high boiling points from hydrogen bonding
- Solubility in water for smaller alkanoic acids
