How does the length of the
carbon chain effect the
melting points and boiling
points of hydrocarbons?
The longer the carbon chain the
higher the melting and boiling
points.
Which of the following would
you expect to have the
highest boiling point?
(1) CH3CH2CH2CH2CH3
(2) CH4
(3) CH3CH3
(1) CH3CH2CH2CH2CH3
Are hydrocarbons soluble in
water? Why or why not?
They are not soluble in water as
they are non-polar.
What are isomers?
Isomers have the same molecular
formula but different molecular
structure. The double or triple
bond will be in a different location

Draw the structural formula
and give the molecular formula
- butane
Draw the structural formula
and give the molecular formula
- 1 – hexene
Draw the structural formula
and give the molecular formula
- 2 – pentyne
Draw the structural formula
and give the molecular formula
- ethyne
Draw the structural formula
and give the molecular formula
- 4- nonene
Why is no number used in the
names “ethene” and “propene”?
There is only one place you can put
the double bond for both
molecules.
Why is the name 3 - pentyne
incorrect?
It would be 2 pentyne as you always
have to name using the smallest
hydrocarbon chain.
Describe and explain the
relationship between the sizes
of hydrocarbon molecules and
their boiling points.
The longer the hydrocarbon molecule
the higher the melting and boiling
point.
is a method used to separate
the components of petroleum
It involves the process of
distillation, making use of
the differences in boiling
points of the different
hydrocarbons.
fractional distillation
To make fuels better for
internal combustion engines
straight chain hydrocarbons
are broken down into shorter
branched chain hydrocarbons
process of cracking
a particular combination of
atoms that contributes to
the physical and chemical
characteristics of a
substance
functional group
What type of functional group
does an alcohol contain
OH (hydroxyl) group
Give the physical properties
of alcohols
• polar
• higher melting and boiling points
the alkanes of similar chain length
• longer the carbon chain is the
higher the boiling point will be
Write the equation for the
complete combustion of
methanol.
2CH3OH + 3O2 ===> 2CO2 + 4H2O
Name the - CH3CH2OH

Draw the structural formula
for - 1 – propanol
Draw the structural formula
for - ethanol
Draw the structural formula
for –, 1 - hexanol
What type of functional group
does an ether contain?
R – O - R
. Explain why methanol has a
higher melting point than
methane.
It contains an hydroxyl so is polar
and forms hydrogen bonds and will
therefore take more energy to split
the bonds thus causing an higher
melting point.

compounds in order of
increasing boiling point.
1 – pentanol, decane, 1 –
decanol, pentane
Pentane, 1-pentanol,decane, decanol
