Organic Chem Exp Flashcards
What is a dehydration reaction//elimination reaction
Water is loss
What are the chemicals used in preparation of ethene
Aluminium oxide
Ethanol in Glass wool
Why is ethanol and aluminum oxide used ?
Ethanol is used to make theme gas
Aluminum oxide is used as a catalyst and a dehydrating agent
Properties of ethene
Colorless
Sweet smell
Insoluble in water
Add limewater it’ll turn milky
Add bromine water (turn red to colorless) or acidified potassium permanganate (purple to colorless)
Why use acidified potassium permanganate
If h+ ions are not present, the potassium permanganate cannot act as an oxidizing agent sine the h+ ions are needed for the reaction
What do you use to make ethyne
In order Water Calcium carbide Acidified copper sulfate Ethyne
Properties of ethyne
Colorless sweet
Insoluble
Burns lighted taper in luminous smoke
Bromine
Potassium permanganate
Ethyne : what substance is left in the Büchner flask
Calcium hydroxide
Use for ethyne gas
Welding and cutting metals
