Question Answer
Acid-Base RxA reaction in which an acid ⇒ donates proton to a base
Acid disassociation constantA measure of the degree to which an acid disassociates
AcidityA Measure of how easily a compound gives up a proton
Anti bonding molecular orbitalA molecular orbital results when two atomic orbitals with opposite phases interact. Electrons in an antibonding orbital ⇒ decrease bond strength.
Atomic Number( symbol A) - how many protons (or electrons) a neutral atom has
Atomic Weight: (Z) average mass of the element, protons + neutrons
Question Answer
AufbauAufbau addresses. Law that tells that electron will go into the available orbital w/the lowest energy
BaseA substance that accepts a proton
BasicityDescribes the tendancy of a compound to share its electrons with a proton
Bond dissociation energyThe amount of energy required to break a bond homolytically (ie. each atom has custody of 1 bonding electron) ⇒ or the amount of energy Released when a bond is Formed.
Bonding molecular orbitalA molecular orbital that results when 2 atomic orbitals (with the same phase Interact). NB: electrons in a bonding orbital ⇒ ++ bonding strength
Bond lengthInternuclear distance between 2 atoms at minimum energy (maximum stability).
Bronstead AcidA substance that donates a proton
Bronstead BaseA substance that accepts a proton
Buffer solutionSolution of weak acid and its conjugate base
CarboanionSpecies containing a negatively charged carbon
CarbocationSpecies containing a + charged carbon
Condensed structuredoes not show all covalent bonds
What is the -log?Is the EXPONENT ie. 10 to the 2nd power is 10x10
Henderson-Hasselbalch EqNpKa = pH + log [HA] / [A-]
Hund RuleWhen there are degenerate orbitals, an electron will occupy an empty orbital ⇒ before it pairs up with another electron
Hybrid OrbitalWhen an orbital is blended, or formed by mixing/hybridizing of atomic orbitals
Hydride IonA Negatively charged Hydrogen OR a hydrogen atom w/out its electron
Hydrogen Ion-ProtonA positively charged hydrogen [OR a hydrogen w/extra electron-]
Inductive electron withdrawalPull of electrons through sigma bonds by an atom/group of atoms
Ionic BondBond formed attraction of opposite charges
Ionic CompoundCompound ⇒ is positive ion + neg ion
Ionization energyThe energy required to Remove an electron from an atom
IsotopesAtoms w/same number of protons [but different number of neutrons]
Lewis AcidSubstance that accepts electron pair
Lewis baseSubstance that donates electron pair. Stephen Lewis_Baseball donor.
Lone pair electrons LPValance electrons ⇒ NOT used in bonding
