Properties of Alkanes Flashcards
1
Q
What are alkanes?
A
a homologous series of hydrocarbons that have only single bonds
2
Q
What is the general formula for alkanes?
A
CnH2n+2
3
Q
How do trends work with alkanes?
A
as the length of the carbon chain increases there are trends in the properties?
4
Q
What is a carbon chain?
A
the longest chain of carbons in an alkane (it can bend aswell)
5
Q
How does the boiling point of an alkane change their state with chain length?
A
low bp = gas at room temp (shortest chains)
mid bp = liquid at room temp (mid chains)
high bp = solid at room temp (longest chains)
6
Q
Which types of alkanes are more flammable?
A
shorter alkanes are more flammable and can ignite more easily
7
Q
What is the trend for colour of alkanes?
A
the longer the carbon chain the darker the colour the alkane is
