Alcohols, Carboxylic Acids And Esters Flashcards
Alcohols ending and functional group
Carboxylic acid ending and group
Alcohol - ending (ol) group is (hydroxyl)
Carboxylic acid - (oic acid). Carboxyl
Why can alcohols form hydrogen bonds
Because of their polar OH group
How to tell if the acid is stronger
It will have a higher concentration of H+ ions
Plane the three types of alcohols and how many hydrogens are attached to the carbon molecule
Primary (2)
Secondary(1)
Tertiary(0)
How can you tell if an ester has formed?
Change in smell and or an immiscible layer
2 Uses for an Ester
Flavourings and deodorants
Why do you use a water bath when making an ester?
It is highly flammable
Why is a condensor used in making an ester?
To prevent loss of the ester
Esters are made from?
Alcohols and carboxylic acids
What is the link called when the condensation joining of carboxylic acids and alcohols undergo
An ester link
How are esters formed?
Name this process?
Condensation of alcohols and carboxylic acids
- esterfication
What is formed when carboxylic acids react with bases? Give an example
Salts are formed.
Example (sodium ethanoate)
Name the catalyst for esters?
Concentrated sulfuric acid
