1.4 Structure and Bonding Flashcards
Name the 3 different Intramolecular Bonds
Covalent
Ionic
Metallic
What kind of bond is formed when there is no difference in electronegativity?
Non Polar
Name the 3 different Intermolecular Bonds
London Dispersion Forces (LDFs)
Permanent dipole - permanent dipole (PD-PD)
Hydrogen
What are LDFs?
They are the attraction between temporary dipoles
What are PD-PDs?
They are the attraction between permanent dipoles
What are Hydrogen Bonds?
They are the attraction between permanent dipoles where H is bonded to either N/O/F
Where do you find LDFs?
They are in everything that has electrons
Where do you find PD-PDs?
In polar molecules
Where do you find Hydrogen Bonds?
In polar molecules (H-N/O/F)
How do LDFs arise?
They are formed due to the uneven movement of molecules
How to PD-PDs arise?
The form due to a difference in electronegativity values
How do Hydrogen Bonds arise?
they form due to a big difference in electronegativity values
What is Viscosity?
How easily a substance flows
What can be used to describe solubility?
Like dissolves like
What is a molecule if it is symmetrical?
Non Polar
