Chapter 1 - Bonding And Isomerism (w/ Functional Groups) Flashcards
(47 cards)
Deal only with substances obtained from living matter
Organic Chemistry
proved that organic compounds can
be synthesized in the laboratory
Friedrich Wohler
Smallest particle of an element that retains all chemical properties of that element
Atoms
Characteristics of a nucleus (2)
- Positively-charged
- Contains most of the mass of the atom
Location of protons and neutrons
Nucleus
Location of electrons
Electron cloud
Same number of protons but different number of neutrons and nuclear decay processes
Isotopes
Equation for Mass Number
of protons (Z) + # of neutrons
G.N. Lewis developed this as one of the earliest successful pictures of chemical bonding
Octet Rule
What is the noble gas electron configuration?
8 valence shell electrons in 4 orbitals
Form between a metal form the left of periodic table and a nonmetal from the right
Ionic Bonding
Minimum amount of energy required to remove an electron
Ionization energy
Amount of energy released when an electron is added
Electron Affinity
What happens to the attractive forces and repulsive forces in ionic bonding?
- Attractive forces between ions of opposite charges are maximized.
- Repulsive forces between like charges are minimized.
Bonding that shares electrons between two nonmetals, or metalloid to nonmetal
Covalent Bonding
Simplest example of Covalent Bonding
H2
True or False: The more e- pairs that atoms share the closer the atoms are pulled together
True
(Triple bond < double bond < single bond)
True or False: Carbon is either strongly electropositive nor strongly electronegative
False
(It is neither)
Ability of an element to form chains of its own atoms through covalent bonding
Catenation
Molecular fragment with an odd number of unshared electrons
Radical
Ability of an atom to attract bonding e to itself
Electronegativity
Electron pair is not shared equally between two atoms
Polar Covalent Bonds
True or False: Electronegativity of elements increases from left to right across the period, and from bottom to top within a group
True
Number of bonds that an atom of the element can form
Valence
