7 FUNDAMENTAL UNITS OF MEASUREMENT
length

time
electric current
temperature
luminous intensity
amount of substance
- “Within molecules”, stronger
- E.g., Ionic/electrovalent, and covalent bonds
INTRAMOLECULAR FORCES
- “Between molecules”
- Easy to break
- Attractive force BETWEEN neighboring molecules
- E.g., Van der Waals Forces, H-bonds
INTERMOLECULAR FORCES
When molecules interact with each other, they do so by the actions
REPULSIVE & ATTRACTIVE FORCES
“Together”
ATTRACTIVE FORCES
like molecules
COHESIVE FORCES
unlike molecules
ADHESIVE FORCES
“Apart”
REPULSIVE FORCES
at what distance are the attractive and repulsive forces EQUAL
3 - 4 x 10^-8 cm in distance
BOND TYPE & ELECTRON SHARING
less than 0.5
NON POLAR, EQUALLY SHARED
BOND TYPE & ELECTRON SHARING
0.5 - 1.9
POLAR COVALENT, UNEQUALLY SHARED
BOND TYPE & ELECTRON SHARING
greater than 1.9
IONIC, TRANSFER –> element with higher EN
ELECTRONEGATIVITY DIFFERENCE
non polar, equally shared
less than 0.5
ELECTRONEGATIVITY DIFFERENCE
polar covalent, unequally shared
0.5 - 1.9
ELECTRONEGATIVITY DIFFERENCE
ionic, transfer of electrons
greater than 1.9
in polar covalent bonding, the unequally shared electron favors which element
element with higher EN
- this has a significant impact on attractive and repulsive forces
- reliant on electronegativity
POLARITY
ability to ATTRACT electrons
ELECTRONEGATIVITY
relationship between EN & polarity
the higher the EN, the more polar the molecule
A molecule with NO POLAR BONDS
NONPOLAR
A molecule with ONE POLAR BOND
POLAR
two factors that dictates the polarity of a molecule
POLARITY OF INDIVIDUAL BONDS
OVERALL SHAPE
OH is present
POLAR
hydrocarbon chain
NONPOLAR
Van der Waals attractive forces
o Keesom forces
o Debye forces
o London forces
charged particle
DIPOLE
nonpolar, partial charging, happens in organic compounds only
INDUCED DIPOLE

KEESOM forces has what effect
ORIENTATION effect
- Dipole-dipole forces / Ion-dipole interaction
- Occur when polar molecules possessing permanent dipoles, having partial positively charged and a partial negatively charged end, interact. → Polar molecule + Polar molecule
KEESOM FORCES
DEBYE forces has what effect
INDUCTION EFFECT
- Dipole-induced dipole forces
- Occur when polar molecules produce a TEMPORARY ELECTRIC CHARGE DIPOLE in nonpolar molecules → polar molecule + non polar molecule
DEBYE FORCES
LONDON forces has what effect
DISPERSION EFFECT
- Induced dipole-induced dipole forces
- Occur in by INTERNAL VIBRATIONS in nonpolar molecules to produce attraction that arises because of FLUCTUATING DIPOLES in neighboring atoms → non polar molecule + non polar molecule
LONDON FORCES
WEAKEST force
LONDON FORCES
electrostatic force of attraction
KEESOM
hydrogens can also exist as
DIATOMIC ATOM
basis for standard polarity
WATER, if madissolve sa water then it is polar
all IONIC BONDS are
POLAR
if an atom gets a FORMAL CHARGE
IONIC BOND
- Molecules that are polar are attracted to EITHER POSITIVE OR NEGATIVE CHARGES → ion + polar molecule
ION-DIPOLE
- The forces of attraction are induced by the CLOSE PROXIMITY of a charged ion to the nonpolar molecule → ion + nonpolar molecule
ION - INDUCED DIPOLE
can be intramolecular and intermolecular
HYDROGEN BOND
- It is the bond that cause the attraction of H atom for a strongly electronegative atom such as O, N, F, and S.
- It is a STRONG TYPE OF DIPOLE-DIPOLE interaction.
- It is PARTLY COVALENT in nature.
- Responsible for the unusual properties of water such as HIGH BOILING POINT
