Are carboxylic acids, esters, and amides all polar?
Yes
Can carboxylic acids, esters, and amides all hydrogen bond?
No, carboxylic acids and amides are able too
What are the most common carboxylic acids?
Acetic acid and citric acid
How are dioic acids different from carboxylic acids?
They have two -COOH groups
What can carboxylic acids do that ketones and aldehydes cannot?
Substitution reactions
_____ is made when there is a carbonyl group substitution reaction. To reverse it you need a ______ reaction
Esters
Hydrolysis
What is the most significant property of carboxylic acids?
They can surrender the H of their carboxyl group to bases and establish acid base equilibrium in aqueous solutions
T or F
Carboxylic acids cannot hydrogen bond with each other
False, they can

The longer the carbon chain the lower or higher the melting/boiling point?
Higher
Carboxylic acids with more than ____ in their carbon chain are waxy odorless solids
9
What is the simplest carboxylic acid?
Formic acid
Can esters hydrogen bond with each other and water?
Not each other but can with water
T or F
Esters have higher boiling point than carboxylic acids
False
____ are colorless, volatile liquids with pleasant odors
Esters
Are esters soluble in water? Are the flammable?
Somewhat soluble
Very flammable
T or F
Esters are bases in aqueous solutions
False, neither acids nor bases in aqueous solutions
Can amides hydrogen bond with each other?
1 degree= yes
2 degree=yes
3 degree=no
Do amides have a higher boiling point than carboxylic acids?
Yes because they can hydrogen bond to each other
