Secondary alcohols can be oxidised to these. (7)
This method of manufacturing ethanol gives an impure product. (12)
The acid catalyst used in the manufacture of alkenes from alcohols by
elimination. (9)
The job of the phosphoric acid in the hydration of alkenes. (8)
A key condition for fermentation. (5)
Ketones are resistant to this and show a negative reaction with Fehlings
solution. (9)
The product formed when ethanol is reacted with acidified potassium
dichromate. (7)
The colour of potassium dichromate when it has finished oxidising an
aldehyde to a carboxylic acid. (5)
When produced by fermentation, ethanol is this type of fuel. (7)
The colour produced when Fehlings solution is gently heated with an
aldehyde. (5,3)
The molecule that is eliminated when alcohols are converted to alkenes. (5)
An alcohol with two R groups. (9)
A reagent used to distinguish between aldehydes and ketones. (7)

This type of alcohol is the least easy to oxidise. (8)
Fermentation is this type of process and so is expensive. (5)
The process by which alkenes are converted to alcohols. (9)
The product formed by reacting butan-2-ol with acidified potassium
permanganate. (8)
Ethanol produced by fermentation is said to be carbon ....?..... (7)
A reaction condition for the oxidation of secondary alcohols. (4)
The positive result for a test using Tollens reagent with an aldehyde. (6,6)
To further oxidise an aldehyde to a carboxylic acid this much oxidising agent
is needed. (6)
The material from which most monomers are derived. (3)
The first stage in the oxidation of a primary alcohol produces one of these.
(8)
Oil is an example of this type of resources that will eventually run out. (6)
