The temp at which the vapour pressure of a substance equals atmospheric pressure. The stronger the IM forces, the higher the bp.
The temp at which the solid and liquid phases of a substance are at equilibrium. The stronger the IM forces, the higher the mp.
The pressure exerted by a vapour at equilibrium with its liquid in a closed system. The stronger the IM forces, the lower the vp.
A series of organic compounds that can be described by the same general formula OR in which one member differs from the next with a CH₂ group.
A bond or an atom or a group of atoms that determine the physical and chemical properties of a group of organic compounds.
Chain, positional, and functional.
a molecule that consists of a large number of atoms
a large molecule composed of smaller monomer units covalently bonded to each other in a repeating pattern
small organic molecules that can be covalently bonded to each other in a repeating pattern
a chemical reaction in which monomer molecules join to form a polymer
a reaction in which small molecules join to form very large molecules by adding on double bonds
a polymer formed when monomers (usually containing a double bond) combine through an addition reaction
molecules of two monomers with different functional groups undergo condensation reactions with the loss of small molecules, usually water
a polymer formed by two monomers with diff functional groups that are linked together in a condensation reaction in which a small molecule, usually water, is lost
min energy needed for a reaction to take place
the unstable transition state from reactants to products
the change in concentration of reactants or products per unit time
Factors that affect rate
nature of reacting substances
concentration (pressure for gasses)
presence of a catalyst
substance that increases the rate of a chemical reaction without itself undergoing a permanent change
chem → electr. energy
has self-sustaining electrode reactions
solution/liquid/dissolved substance that conducts electricity through the movement of ions
