Chemistry Unit 10 (Course book 4th
edition) Exam with Complete Solutions
(Example of an) Equation for cracking of Octane - ✔✔C8H18 -(Catalyst)-
(heat)-> C3H4 (ethene) + C6H12 (hexene)
(Word) formula for converting glucose into ethanol - ✔✔Glucose -(yeast)->
ethanol + carbon dioxide
2 reactions used to form ethanol - ✔✔Hydration reaction + fermentation
2 types of polymerisation - ✔✔Addition polymerisation and condensation
polymerisation
3 rules to keep in mind when naming halides - ✔✔1. Longest chain
possible (of carbon)
2. Smallest number possible (eg 2, 2 dimethyl butane not 3, 3 dimethyl
butane (C6H14))
3. Follow alphabetical order (eg 2-bromo, 3-chloro, 3-methyl butane)
4 examples of inorganic Carbon compounds - ✔✔CO, CO2, CO3, HCO3
, Adding a halogen is called a ______ reaction - ✔✔Halogenation rxn
Adding a halogen to an alkane is also called a __________ reaction -
✔✔Substitution rxn
Adding a halogen to an alkene is also called an __________ reaction -
✔✔Addition rxn
Adding hydrogen to alkanes can also be known as a (________ reaction)
on top of being called a halogenation reaction - ✔✔Substitution reaction
Alkanes are considered to be ______ reactive (very/not very) - ✔✔Not very
Alkanes can only undergo a substitution reaction with _______ -
✔✔Halogens
As you go down the alkene group, the melting/boiling point _______
(increases/decreases) - ✔✔Increases
Can you get pure ethanol; why or why not? - ✔✔No because of the
presence of water - never 100% pure
Carboxylic acids general formula - ✔✔CnH2n+COOH
Chemical compound for vinegar - ✔✔CH3COOH
Chemical equation for combustion of ethene - ✔✔C2H4 + 6O2 -> 2CO2 +
H2O + Energy
