7Bond Order
The number of bonds between a pair of atoms in a molecule
8Unsaturated compounds
Molecules that possess one or more double or triple bonds (or a ring) as a part of their structure
9Molecular formula
The number and type of different atoms present in a compound
10Structural formula
Provides same info as MF but also shows the pattern of connectivity between the atoms of the molecule
11Isomers
Molecules that have the same number and types of atoms (same MF) but different arrangements of the atoms
12Constitutional/structural isomers
Compounds with the same MF but different connectivity between the atoms in their structural formulae
13Heteroatoms
Atoms other than carbon or hydrogen bonded to the carbon skeleton at various positions
14Functional groups
Heteroatoms bonded together in organic molecules in specific patterns
15Condensed formulae
Shows all the atoms but few (or non) of the bonds in the structure
16Bond-line formulae
Shows all the bonds and none of the atoms, except for heteroatoms and hydrogens attached to heteroatoms
17Formal charge
The elctrical charge possessed by an atom when bonded in a molecule
18Formal charge equation
Group # - Dots + Dashes
19Electrically neutral
formal charge of zero
20Anionic
negative formal charge
21Cationic
positive formal charge
22Resonance structures
Two or more structural formulae of a molecule (or polyatomic ion) with identical arrangements of the atoms but different arrangements of the electrons in each
23Hybrid form
Also resonance hybrid, an average or blend of all of the individual resonance structures that can be drawn for that molecule
24Quantum mechanics
The branch of science that deals with the mathematical description of the motion and interaction of subatomic particals
25Orbital
A region of space around an atom in which there is a high probability of finding an electron
26S atomic orbitals are
spherical
27P orbitals are
dumbell shaped
28Node
A place in an orbital where there is zero probability of finding an electron
29Ground state
The lowest energy state of an atom or other particle
30Bonding molecular orbital
A space for electrons to reside, created by the overlapping of atomic orbitals
31Theory of atomic orbital hybridization
Atoms do not use their native atomic orbitals in the valence shell to make bonds directly but instead blend or mix them together to make new, or or hybrid, atomic orbitals and then use the hybrid orbitals to make bonds
32Valence shell electron pair repulsion theory
A shortcut for describing the shape around atoms in molecules
33Electronic geometry
Refers to the shape assumed by the pairs of electrons themselves
34Molecular geometry
The shape assumed by the position of atoms bonded around an atom
