ANSWER: Melting/Boiling point increases
Alkanes are considered to be ______ reactive (very/not very) - ANSWER: Not very
Combustion of methane - ANSWER: CH4 + 2O2 -> CO2 + 2H2O + energy
Combustion of ethane - ANSWER: 2C2H6 + 7O2 -> 4CO2 + 6H2O + energy
Halogen alkanes are ________ reactive than alkanes (more/less reactive) - ANSWER: More reactive
What is one way to make alkanes react more vigorously? - ANSWER: Halogenation of Alkanes
Reaction between methane and chlorine - ANSWER: CH4 + Cl - (UV light)-> CH3CL + HCl

(Example of an) Equation for cracking of Octane - ANSWER: C8H18 -(Catalyst)-(heat)-> C3H4 (ethene)
+ C6H12 (hexene)
:
3 rules to keep in mind when naming halides - ANSWER: 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)
What are the 2 main reactions alkanes undergo? - ANSWER: Combustion and Halogenation
Adding hydrogen to alkanes can also be known as a (________ reaction) on top of being called a
halogenation reaction - ANSWER: Substitution reaction
Alkanes can only undergo a substitution reaction with _______ - ANSWER: Halogens
Adding a halogen is called a ______ reaction - ANSWER: Halogenation rxn
Adding a halogen to an alkane is also called a __________ reaction - ANSWER: Substitution rxn
Adding a halogen to an alkene is also called an __________ reaction - ANSWER: Addition rxn
Naming a halogen alkane depends on _______ - ANSWER: The location of the halogen
Write/draw 1-bromo propane - ANSWER: CH3 - CH2 - CH2 - Br
, General formula for alkanes - ANSWER: CnH2n+2
General formula for alkenes - ANSWER: CnH2n
General formula for alcohols - ANSWER: CnH2n+OH
What is the main difference between alkanes and alkenes? - ANSWER: Alkenes have a double
bond/alkanes don't
(+ General formula)
Double bonds can also be referred to as _______ - ANSWER: Unsaturated bonds
The presence of double bonds makes an alkene __________ reactive than an alkane (more/less
reactive) - ANSWER: More reactive
As you go down the alkene group, the melting/boiling point _______ (increases/decreases) -
ANSWER: Increases
How do you test to differentiate alkanes and alkenes? - ANSWER: Test for saturation
What do you need to consider when naming an alkene? - ANSWER: Position of double bonds
When is the position of double bonds assigned (in an alkene)? - ANSWER: In its name - eg pent-1-ene
vs pent-2-ene
In a test for saturation, alkanes undergo what reaction? - ANSWER: Substitution reaction
In a test for saturation, alkenes undergo what reaction? - ANSWER: Addition reaction
The word for light can also be abbreviated as _______ in a chemical equation - ANSWER: HV (eg HV
UV is UV light)
Single bonds are __________ (saturated/unsaturated) - ANSWER: Saturated
Double bonds are __________ (saturated/unsaturated) - ANSWER: Unsaturated
Saturated bonds are __________ than unsaturated bonds (healthier/not healthier) - ANSWER: Not
healthier
Test for saturation between ethane and Br (include the type of reaction, any catalysts, how you know
it is ethane not ethene, and whether its bond is saturated/unsaturated) - ANSWER: CH3 - CH3 + Br2 -
(HV UV) -> CH3 - CH2 - CH2 - Br + HBr
* Substitution rxn
* Color will not change, it'll stay the same red/brown color
* Saturated bond
Test for saturation between ethene and Br (include the type of reaction, any catalysts, how you know
it is ethane not ethene, and whether its bond is saturated/unsaturated) - ANSWER: CH2 = CH2 + Br2 -
(HV UV) -> Br - CH2 - CH2 - Br
* Addition rxn
* Red/brown color -> clear color
* Unsaturated bond
What are the 4 main reactions alkenes undergo? - ANSWER: 1 - Combustion rxn
2 - Halogenation
3 - Hydrogenation
