Chapter 15 Flashcards
What is a carbonyl group?
C=O
What is the geometry and angle of the carbonyl group?
Planar/ flat (trigonal planar around carbonyl group)
120 degrees
Can ketones and aldehydes hydrogen bond?
No, not to each other since there’s no H starched to the oxygen
Why do ketones and aldehydes have a lower boiling point than alcohols?
Because ketones and aldehydes cannot hydrogen bond with each other
What is needed to hydrogen bond?
N-H or O-H
T or F
Ketones and aldehydes are polar, are typically liquids, have a distinctive odor, and are not water soluble bc they cant hydrogen bond with water
False, the can hydrogen bond with water
Are simple ketones or simple aldehydes more toxic?
Simple aldehydes
Are they soluble in water?
Yes the simple ones
T or F
Ketones and aldehydes can be oxidized
False, only aldehydes since ketones don’t have H
The oxidation of aldehydes produces what?
Carboxylic acids
What is the simplest aldehyde? And what’s it’s formula?
Formaldehyde, HCHO
What is the chemical formula for acetaldehyde? And what’s a characteristic of it?
CH3CHO
It’s boils close to room temp
What is the chemical formula for acetone?
