Bonding Flashcards
1
Q
How do you know if element is non-polar?
A
If the Electronegativity difference is 0-0.4
2
Q
How do you know if element is Polar?
A
0.5-2.0
3
Q
How do you know if element is Ionic?
A
> 2.0
4
Q
Is LiBr polar or non polar? Li=1.0 Br=3.0
A
3.0-1.0=2.0 Therefore it is polar
5
Q
What are Van Der Waals?
A
Van Der Waals forces are very weak and short lived between any and all particles
6
Q
What are Dipole-Dipole?
A
When bond is polar than it creates a partial negative and positive charge, therefore the force is between two elements with opposite charge
7
Q
What are Hydrogen Bonds?
A
When area of partial positive charge comes from hydrogen atom we call the dipole-dipole attraction a hydrogen bond
8
Q
What are Ion Dipoles?
A
When an Ion and a element is attracted
