Carboxylic Acids and Esters
Products of acid (Usually H2SO4 or HCl) hydrolysis of Esters are:
Esterification produces:
- carboxylic acid and alcohol: Structure:
Products of Base (usually NaOH or KOH) hydrolysis of Esters are:

Saponification results in the carboxylic acid salt and the corresponding alcohol.
Carboxylic Acid Structure:
Ester Structure:
Common name for Methanoic Acid:

Formic Acid: found in Bee or Ant Stings: Structure:
Common name for Ethanoic Acid:

Acetic Acid: Water & Vinegar Structure:
Common name for Propanoic Acid:
- Propionic Acid: Structure:
Boiling points in Carboxylic acids are higher than alcohols, ketones and aldehydes because of:
- Polar -OH groups forming hydrogen bonds.
- Dipole-dipole attractions increase boiling points.
- Formation of Dimers (Carboxylics can do this) increases Boiling Point.
4 Carboxylic acids that are soluble in water:
- Methanoic acid
- Ethanoic acid
- Proanoic acid
- Butanoic acid
3 slightly soluble carboxylic acids in HOH:
- Pentanoic acid
- Hexanoic acid
- Benzoic acid
Carboxylic acid reacts with an alcohol to form an:

Ester and HOH
A monosaccharide that contains 4 carbon atoms, one of which is an aldehyde group is classified as a(n):

aldotetrose
In a disaccharide, two monsaccharides are joined by what kind of bond?

glycosidic
Under acid hydrolysis conditions, starch is converted to:
- Maltose
- Glucose
Maltose can be classified as a(n):

Disaccharide.
Aluminum hydroxide

Al(OH)3
Monosaccharide produced upon hydrolysis of Amylopectin:

Glucose
When a carboxylic acid and an alcohol react in the presence of an acid catalyst usually (H2SO4) the reaction is called:

Esterification.
