Alcohols Flashcards
1
Q
Oxidation of a primary alcohol (distillation)?
A
Primary Alcohol+ [o] = Aldehyde+ Water
H2SO4 + K2Cr2O7
2
Q
Oxidation of a primary alcohol (distillation) again?
A
Aldehyde+ [o] = Carboxylic Acid
H2SO4 + K2Cr2O7
3
Q
Oxidation of a primary alcohol (reflux)?
A
Primary alcohol+ 2[o] = Carboxylic Acid + Water
4
Q
Oxidation of a secondary alcohol?
A
Secondary Alcohol+ [o] = Ketone+ Water
Must be distilled as secondary alcohols can only be oxidised once
H2SO4 + K2Cr2O7
5
Q
Can you oxidise a tertiary alcohol?
A
No
6
Q
What is the colour change?
A
Orange to green
7
Q
Are alcohols a good medium?
A
Yes as they’re soluble and can form hydrogen bonds
More OH groups= more H bonds
8
Q
Are alcohols viscous?
A
If there are more OH’s more H bonds are needed to be broken therefore the alcohol is more viscous
