Module 3 Flashcards
Binding forces that join atoms together to create a compound
Intramolecular forces
What do intramolecular forces create?
A compound
In intramolecular forces, what are you joining?
Atoms together
Types of intramolecular forces
- Ionic bond
- Covalent bond
- Metallic Bond
Transfer of electrons
Ionic bond
Sharing or electrons
Covalent bonds
Unequal valence electrons means
Polar Covalent bond
Equal valence electron means
Non-polar Covalent Bonds
Bond based on electrostatic attraction between metal ions and delocalized electrons
Metallic bond
Forces that hold molecules and compound together to create substance
Intermolecular forces
What does intermolecular forces create
Substance
In intermolecular forces, what do u join?
Molecules and compounds
4 types of intermolecular forces
- Ion dipole
- Dipoledipole
- Hydrogen bond
- London dispersion
Chemical bond between atoms
Intramolecular forces
Attractive or repulsive forces between compounds
Intermolecular forces
Bond that Forms a compound
Intramolecular forces
Bond that forms a substance
Intermolecular forces
kJ/mole for intramolecular forces
50-200
kJ/mole for intermolecular forces
1-12
Ion dipole force occurs between
Ion and a polar molecule
Charge of an Ion Dipole force
Strong electrostatic interaction
Why is ion dipole have a strang electrostatic interaction
Because of the full energy
Dipole dipole occurs between
2 polar molecules
Polar molecules are
- Permanent seperation of charges
- Partially charges
What electrostatic force has dipole dipole have
Weak electrostatic attraction
Why does dipole dipole force have weak electrostatic attraction
Because of the partially charges
A special type of dipole dipole force
Hydrogen bond
Why is Hydrogen bond a special type of dipole dipole force
2 polar molecules but has hydrogen interacting with a high electronegativity elements
What are the high electronegativity elements hydrogen bond with to occur hydrogen bond
Fluorine, Oxygen, Nitrogen
Weakest type of intermolecular force
London dispersion
Why is london dispersion the weakest force
Because of its temporary charges
London dispersion force occurs in
- Non polar
- Noble gases
London dispersion is also known as
Induced dipole induced dipole forces
Order of intermolecular forces based on lowest to highest strenght of attraction
- London disp
- Dipole dipole
- Hydrogen bond
- Ion dipole
High boiling point is _____ IMFA
High
High melting point is ____ IMFA
High
A more rigid or solid state is a _____ IMFA
High
A more viscousity is related to ____ IMFA
High
Why is that that high IMFA are more viscous or solid
Molecules are held together tighter
Attraction between different molecules
Adhesion
Attraction between same molecules
Cohesion
Strong IMFA relation to cohesion and adhesion
High IMFA = hugh cohesion - weak adhesion
Adhesion > cohesion
Concave
Cohesion > adhesion
Convex
A high surface tension is cohesion or adhesion
Higher cohesion
High IMFA is ____ liquid surface tension
High
Ability to rise in a tube or space against the force of gravity
Liquid capillary action
Relationship of liquid capillary action to cohesion and adhesion
High capillary action = high adhesion = low cohesion
High IMFA is ____ capillary action
Low
The amount of substance that can dissolve in a given amount of solvent at a specific temp and oressure
Solubility
Solubility basically means
Like dissolves like
Tinutunaw
Solute
Pang tunaw
Solvent
Disordered arrangement of particles, with no regular, repeating pattern.
Amorphus solids
have a regular, repeating pattern of particles, forming a crystal lattice.
Crystalline solids
They lack a definite shape or structure
Amorphus solids
They have definite shape and structure
Crystalline solids
