Alcohol Flashcards
1
Q
As their size increases
A
The strength of London forces also increases
2
Q
Alcohol group
A
CnH2n+1OH
3
Q
Alcohol can be made by halogenalkane
A
Halogenoalkane——-> alcohol
Aqueous hydroxide
It occurs through nucleophilic substitution
4
Q
Alcohol key characteristics
A
- strength of London forces increases
- melting point and boiling points
- as length increases solubility decreases
5
Q
Oxidation of alcohols
A
Primary alcohol is oxidised to aldehyde
Secondary alcohol is oxidised to ketone
Tertiary alcohol can’t be oxidised.
6
Q
Why can’t tertiary alcohol can’t be oxidised
A
Because they don’t have carbon hydrogen bond to break
7
Q
Primary alcohol can oxidised
A
Primary alcohol can be oxidised into aldehyde and further oxides into ketone via reflux
8
Q
What is the oxidising agent to oxidise alcohol
A
Potassium dichromate -K2Cr2O7
Orange to green
