in a few organic reactions the products containes one more carbon atom than the starting material
write the equation for a reaction in which the organic compound bromoethane whicn contains 2 carbon atoms is converted into an organic compound which contains 3 carbon atoms
It is reacted with a nitrile, e.g KCN and the extra C comes from the nitrile. the reaction is nucleophillic substitution hopefully this helps a little The conditions will be on your toolkit, I can't remember them right now, I'm sure some ethanol (aq) comes into it, but don't quote me on that :/ It may just be KCN and reflux actually. But you'll have to check that
ethanol may be converted into propanoic acid in a three stage process which uses ethanol as the only organic compound
C2H5OH (step 1 ) ----> K (step 2) ----> L (step 3) ----> C2H5CO2H
thanks for the help
Okay, so in step 1, we want to convert ethanol into bromoethane by refluxing with HBr (aq). This is step one and K is bromoethane.
Next, we need to add an extra C. This is done by nuclephillic substitution with a nitrile group. So we react bromoethane with KCN and ethanol (aq) and reflux it. This gives L as:
CH3CH2CN.
Now we have our extra carbon and all we need to do is hydrolyse the CN bond to form a carboxylic acid.
And so step 3 is reacting our propanenitrile with concentrated sulfuric acid, water and then reflux.

Hope this helps you
so does n react with sulphuric acid to form nitrogen sulphate
