TRANSCRIPT
What type of carbon to carbon bonds are present in the alkanes
and the cycloalkanes
Single - saturated
Describe the chemical test to distinguish an unsaturated alkene
from a saturated alkane/cycloalkane.
Unsaturated hydrocarbons (alkenes) decolourise bromine
ADDITION
Name the type of reaction which takes place when an unsaturated alkene reacts with bromine,
hydrogen or water
Apart from speeding up the reaction suggest another
reason why a catalyst is used in cracking.
Lower temperatures are used
Why is there a limit to the alcohol concentration produced by
fermentation?
The alcohol kills the yeast.
Name the method of producing industrial ethanol.
Hydration of ethene - adding water onto ethene
C2H4 + H2O C2H5OH
Name the two different types of compounds which react together to
form a ester.
An alcohol and a carboxylic acid.
Name the type of chemical reaction which is taking place.
