Inermolecular Forces Flashcards
1
Q
When can hydrogen bonding take place?
A
Fluorine, nitrogen or oxygen have to be covalently bonded to hydrogen
2
Q
Name two important molecules that have hydrogen bonding
A
Water and ammonia
3
Q
Describe the solubility, boiling point and freezing points of molecules with hydrogen bonding
A
They are soluble in water and have higher boiling and freezing points than non polar molecules of a similar size
4
Q
Which element is the most electronegative?
A
Fluorine
5
Q
What is the weakest type of force?
A
Temporary dipole dipole / van der vials
6
Q
What are the only bonds that can be purely covalent?
A
Bonds between atoms of a single element like diatomic gases such as hydrogen H2 or oxygen O2
7
