GCSE Organic Chemistry - Alkenes with Steam
I’m hoping that you good people of Ephotozine world can come to my sons help.
He’s got his mock GCSE Chemistry exam coming up in the New Year and is working through some past papers and is stuck on one question which I’m hoping someone can answer.
The topic is Alkenes with steam.
When they react with steam, the conditions are
1. Phosphoric(V) Acid Catalyst
2. A temperature of 300oC
3. A pressure of 60-70 atm
He’s stuck on the next part:
C2H4 + O2 = Ethanol (CH3CH2OH)
The product is an --------------?
They react with themselves to make -------- --------?
Thanks
Simon

Ethanol is an alcohol and, together with water, a principal ingredient of vodka.
Are you sure that you've given the correct equation? You should always have the same number of carbon, hydrogen and oxygen atoms on each side. Steam contains two atoms of hydrogen and one of oxygen so that should appear on the LHS of the equation along with the ethylene to make the equation balance.

C2H4 + H2O → C2H5OH
This is an industrial process called the hydration of ethene to produce ethanol. The reaction is Ethene (the alkene) + water (as steam) using a Phosphoric acid catalyst (to speed up the reaction) to produce Ethanol (an alcohol). Ethanol may also be made by fermentation.

When I took my A level chemistry back in 1969, C2H4 was known as ethylene.
