Give the name of an alcohol that could be used in this apparatus to make propene.
Draw the skeletal formula of the alcohol named in (i).
What type of reaction takes place in this case?
During the reaction, the material $X$ turns black. Suggest the identity of the black substance and explain how it is produced during the reaction.
At the end of the experiment, when no more propene is being made, the delivery tube is taken out of the water before the apparatus is allowed to cool. Suggest why this is done.
The material labelled $X$ can be broken crockery, broken brick or pumice. Give the chemical formula of a compound present in one of these materials.
State one further reagent that could be used to make propene from an alcohol.
Give the structural formula of the organic product formed when propene reacts with bromine.
Give the structural formula of the organic product formed when propene reacts with cold, dilute manganate(VII) ions.
Give the structural formula of the organic product formed when propene reacts with hot, concentrated manganate(VII) ions.
Propene may be polymerised. What is the essential condition for such a polymerisation?
The disposal of waste poly(propene) is very difficult. Give one important reason for this.
