Homologous Series Flashcards
(5 cards)
1
Q
What is the homologous series?
A
A group of compounds with the same general formula and different chemical properties
2
Q
What can you use to work out the molecular formula of any member of a homologous series?
A
The general formula
3
Q
Why do molecules in a homologous series have similar chemical properties?
A
Because they have the same functional group. {the functional group is the reactive part of the molecule}
4
Q
What can be seen in the physical properties of compounds in a homologous series?
A
Patterns. Eg. The bigger the molecule is, the higher the melting and boiling point will be.
5
Q
Why are the melting and boiling points higher on larger molecules?
A
Due to the strength of the intermolecular forces that hold the molecules together.
