Intermolecular Forces

weak forces of attraction between polar molecules

Van Der Waal's Forces

very weak attraction between opposite dipoles of different polar molecules

Hydrogen Bonds

Stronger attraction of H dipole +, of one molecule and electron pair of one another molecules

Binary Molecular Compounds

2 non-metals covalently bonded, names end in 'ide', uses numeric prefixes in names

"Like Dissolves Like"

Polar things dissolve in polar things, and non-polar things dissolve in non-polar things

Coordinate Covalent Bonding

when one atom donates an electron pair to form a bond Ex: Carbon Monoxide

Diatomic Molecules

Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, Iodine

VSEPR Theory

Valence Shell Electrons Pair Repulsion
Uses math and 3-D modeling to determine molecule shapes and bond angles

Properties of Polar Molecules

1. Bond between two different atoms
2. Non symmetrical molecules
3. contain pos. and neg. dipoles

Properties of Non-Polar Molecules

1. Bond between the same atoms
2. Symmetrical molecules

Acid

is a compound which when dissolved in water, donates it H+ ions (Protons) to the surrounding water

Ternary Ionic Compounds

3 or more elements in their formulas, always contain at least one polyatomic ion, usually the name ends in 'ite'

Binary Ionic Compounds

2 elements, metal bonded with a non-metal, names end in 'ide', always has a net charge of 0

Cation

ion with a positive charge

Anion

ion with a negative charge

Alkanes

hydrocarbon in which there are only single covalent bonds

Ionic Compound

Salts, formed by the transfer from valence electrons, Metal + Non-Metal, the electronegativity is greater than 1.67 , solid, good solubility and good conductivity, formula unit.

Molecular Compound

Non-Salt, formed by the sharing of valence electrons, Non-Metal + Non-Metal, electronegativity less than 1.67, solid-liquid-gas, solubility is poor, conductivity is also poor, molecules.

Organic Alkanes

Methane, Ethane, Propane, Butane, Pentane, Hexane, Heptane, Octane, Nonane, Decane.
