Van Der Waal's Forces
very weak attraction between opposite dipoles of different polar molecules
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
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
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
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.
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.
