A1: Alcohols Flashcards
1
Q
Dehydration reactions of alcohol
A
Heated under reflux with concentrated H3PO4
makes an alkene and water
2
Q
Reaction of alcohols with hydrogen halides
A
Nucleophilic substitution
Reflux, H2SO4 and NaX so that HX is formed and reacts with the alcohol
Forms water and haloalkane
3
Q
Alcohols properties compared to corresponding alkanes
A
Higher MP (as has hydrogen bonding which is stronger than London forces)
Greater water solubility (O-H bonds are polar and can form hydrogen bonds with water molecules)
4
Q
Oxidation of Primary alcohols with K2Cr2O7/H2SO4 under reflux
A
Carboxylic acid
5
Q
Oxidation of Primary alcohols with K2Cr2O7/H2SO4 under distillation
A
Aldehyde
6
Q
Oxidation of a secondary alcohol with K2Cr2O7/H2SO4
A
Ketone
7
Q
Oxidation of a tertiary alcohol
A
N/A
