Chem 2510 Midterm 1 Terms Questions
and Answers.
Organic Chemistry - Answer The chemistry of carbon and its compounds (organic molecules)
Heteroatoms - Answer Any atom other than C or H used in organic molecules
Covalent Bond - Answer Sharing of electrons between two atoms
Ionic Bond - Answer Electrostatic attraction of two ions with opposite charges
Polar Covalent Bonding - Answer Unequal sharing of electrons due to electronegativity
differences; creates a dipole moment
Dipole - Answer Separation of opposite charges
Constitutional/Structural Isomers - Answer Molecules that have the same molecular format
but differ in connectivity.
1st Rule of Organic Chemistry - Answer Neutral Carbon makes 4 bonds
Resonance - Answer Movement of electrons through p orbitals; delocalization of electron
density
Major Resonance Contributer - Answer Determines most important resonance structure
Atomic Orbitals - Answer Region in space where electrons are likely to be found
Quantum Mechanics - Answer Study of molecular orbitals
Hybrid Orbitals - Answer Mixing of atomic orbitals on the same atom; arises from
hybridization
sp Hybrid - Answer 50% s 50% p, 180 degrees, linear
sp2 Hybrid - Answer 33% s 66% p, 120 degrees, trigonal planar
