Aldehydes & Ketones Flashcards
1
Q
How do you get a Carboxylic acid from an Aldehyde
A
Oxidise it with K2Cr2O7
2
Q
What do aldehydes and unsymmetrical ketones form when they react with KCN
A
Hydroxynitriles which will be enantiomers
3
Q
What are the dangers of KCN
A
KCN is toxic
4
Q
What is the oxidising agent for aldehydes and alcohols
A
[O] from K2Cr2O7
5
Q
What is a reducing agent for aldehydes and ketones?
A
[H-] From NaBH4
6
Q
What is the carbonyl group
A
C=O
7
Q
What type of intermolecular forces does the carbonyl group have
A
Permanent dipole-dipole
8
Q
Is the carbonyl group soluble in water? Why/Why not?
A
Yes as the C=O can form hydrogen bonds. As C chain length increases, solubility decreases.
