MOD 1 Flashcards
Many chemists believed that a “vital force”, a mysterious, presumed property of living things was needed for the formation of organic compounds.
VITAL FORCE THEORY
Vital force theory is abolished by
FRIEDRICH WOHLER
the chemistry of HYDROCARBONS and their derivatives
ORGANIC CHEMISTRY
The SMALLEST PARTICLE of an element that maintains its chemical identity
ATOM
It ESTIMATES the POSITION OF ELECTRONS and quantifies energy levels (a.k.a. shells).
SCHRODINGER WAVE EQUATION
Region of space where electron is MOST LIKELY FOUND.
ATOMIC ORBITALS
SHAPE OF ORBITALS
s
p
d
f
s - spherical
p - dumbbell
d - clover leaf
f- complex
have a LINE drawn between two atoms indicating a 2-electron covalent bond.
KEKULE (LINE BOND)
form as a result of electron TRANSFER
IONIC BONDS
form due to SHARING of electrons.
COVALENT BONDS

less than 0.5
NON-POLAR COVALENT
