Question 1

Why can a tertiary alcohol not be oxidised?

Answer 1

There are no hydrogens on the carbon which the OH group is attached to.

Question 2

What is the partial oxidation of ethanol, and what is the oxidising agent

Answer 2

partial oxidation requires distillation and forms a aldehyde (ethanal)
oxidising agent is acidified sodium dichromate(VI) (H2SO4/ Na2Cr2O7)

Question 3

what is the complete oxidation of ethanol and what is the oxidising agent?

Answer 3

The complete oxidation of ethanol is ethanoic acid (carboxylic acid)
The oxidising agent is acidified sodium dichromate(VI) (H2SO4/ Na2Cr2O7)

Question 4

what functional group is formed when a secondary alcohol is oxidised?

Answer 4

Ketone

Question 5

what type of reaction is dehydration of alcohols?

Answer 5

elimination reaction

Question 6

State the conditions required for the dehydration of alcohols in the laboratory

Answer 6

Hot concentrated sulfuric acid

Question 7

Define a substitution reaction

Answer 7

A reaction in which one atom or group of atoms is replaced by another atom or group of atoms

Question 8

for the halogenation of an alcohol, what type of reaction is it and what mechanism does it use?

Answer 8

Substitution reaction
Nucleophilic substitution

Question 9

for the halogenation of an alcohol what are the reactants needed and why?

Answer 9

NaX (where X is a halide) and H2SO4
This is so the reactants can form a hydrogen halide which is used in
