Intermolecular Forces Flashcards
1
Q
How do LDFS arise
A
Begin with a temporary dipole
2
Q
When does the LDFs strength increase
A
When the number of electrons is increased
3
Q
What is hydrogen bonding
A
Forces of attraction between molecules that contain highly polar bonds
4
Q
How does hydrogen bonding arise
A
A large difference in electronegativity
5
Q
How do you know a bond is hydrogen bonding
A
Is hydrogen js bonded to fluorine, oxygen or nitrogen
6
Q
Why will an element have a higher melting point than others
A
(Bigger the gmf=mkre electrons)
More electrons present, more energy needed to break forces
7
Q
A molecule is polar when it has a pdpd interactions (positive and negative side)
A
