3.
Why are biofuels not completely carbon neutral?
They contain sulfur
They produce CO only
Fossil fuels are used in their production and transport
They do not burn
4.
Which gas is formed from nitrogen in car engines?
NO
CO
SO2
CH4
5.
What type of fission starts free radical substitution?
Heterolytic
Ionic
Catalytic
Homolytic
6.
Why do branched alkanes have lower boiling points than straight-chain isomers?
Fewer covalent bonds
Less surface contact, weaker London forces
They are polar
They hydrogen bond
7.
Which statement best describes Cracking?
Containing only single carbon-carbon bonds.
A saturated hydrocarbon with only C-C and C-H single bonds, general formula CnH2n+2.
Burning in limited oxygen, producing CO and/or carbon (soot) as well as water.
Breaking long-chain alkanes into shorter alkanes and alkenes using heat and/or a catalyst.
8.
Which statement best describes Free radical?
Burning in limited oxygen, producing CO and/or carbon (soot) as well as water.
A family of compounds with the same general formula and functional group, differing by CH2.
Containing only single carbon-carbon bonds.
A species with an unpaired electron, shown with a dot, e.g. Cl•.
9.
Which statement best describes Hydrocarbon?
Burning in limited oxygen, producing CO and/or carbon (soot) as well as water.
A compound containing hydrogen and carbon only.
Describes an activity with no net annual release of CO2 into the atmosphere.
A saturated hydrocarbon with only C-C and C-H single bonds, general formula CnH2n+2.
10.
Which statement best describes Homolytic fission?
A species with an unpaired electron, shown with a dot, e.g. Cl•.
A family of compounds with the same general formula and functional group, differing by CH2.
Breaking of a covalent bond where each atom takes one electron, producing two radicals.
A compound containing hydrogen and carbon only.
