Q

Dipole dipole occurs between

A

2 polar molecules

24
Q

Polar molecules are

A
  1. Permanent seperation of charges
  2. Partially charges
25
What electrostatic force has dipole dipole have
Weak electrostatic attraction
26
Why does dipole dipole force have weak electrostatic attraction
Because of the partially charges
27
A special type of dipole dipole force
Hydrogen bond
28
Why is Hydrogen bond a special type of dipole dipole force
2 polar molecules but has hydrogen interacting with a high electronegativity elements
29
What are the high electronegativity elements hydrogen bond with to occur hydrogen bond
Fluorine, Oxygen, Nitrogen
30
Weakest type of intermolecular force
London dispersion
31
Why is london dispersion the weakest force
Because of its temporary charges
32
London dispersion force occurs in
1. Non polar 2. Noble gases
33
London dispersion is also known as
Induced dipole induced dipole forces
34
Order of intermolecular forces based on lowest to highest strenght of attraction
1. London disp 2. Dipole dipole 3. Hydrogen bond 4. Ion dipole
35
High boiling point is _____ IMFA
High
36
High melting point is ____ IMFA
High
37
A more rigid or solid state is a _____ IMFA
High
38
A more viscousity is related to ____ IMFA
High
39
Why is that that high IMFA are more viscous or solid
Molecules are held together tighter
40
Attraction between different molecules
Adhesion
41
Attraction between same molecules
Cohesion
42
Strong IMFA relation to cohesion and adhesion
High IMFA = hugh cohesion - weak adhesion
43
Adhesion > cohesion
Concave
44
Cohesion > adhesion
Convex
45
A high surface tension is cohesion or adhesion
Higher cohesion
46
High IMFA is ____ liquid surface tension
High
47
Ability to rise in a tube or space against the force of gravity
Liquid capillary action
48
Relationship of liquid capillary action to cohesion and adhesion
High capillary action = high adhesion = low cohesion
49
High IMFA is ____ capillary action
Low
50
The amount of substance that can dissolve in a given amount of solvent at a specific temp and oressure
Solubility
51
Solubility basically means
Like dissolves like
52
Tinutunaw
Solute
53
Pang tunaw
Solvent
54
Disordered arrangement of particles, with no regular, repeating pattern.

55
have a regular, repeating pattern of particles, forming a crystal lattice.
Crystalline solids
56
They lack a definite shape or structure
Amorphus solids
57
They have definite shape and structure
Crystalline solids
