CHM233 Lecture #1: Chapter 1: Remembering General Chemistry Electronic Structure and Bonding
What is Organic Chemistry?
The study of carbon-based molecules
Molecules of life are all carbon-based
o such as proteins, carbohydrates, DNA molecules and nucleic acids
Important to understand organic chemistry is due to the fact that most life molecules are
carbon-based
Will focus on
o Structures and bonding
o Nomenclatures and functional groups
o Reactivity of organic molecules
Periodic Table
Organic molecules contain a few types of elements
o Most important is Carbon
o Nonmetals (right-hand side of the periodic table)
Boron, Carbon, Nitrogen, Oxygen, Fluorine
Aluminum, Silicon, Phosphorus, Sulfur, Chlorine
Bromine
Iodine
o Metals (most of the periodic table is of metals)
Only when working with acid-base reactions due to transfer of ions
Lithium, Beryllium
Sodium, Magnesium
Potassium, Calcium
Columns represent groups aka families
o Main groups: 1A, 2A, 3A, 4A, 5A, 6A, 7A, and 8A
o Have similar behaviors and characteristics to one another
Rows represent periods
o Metals on the left
o Nonmetals on the right
Atomic Structure
An atom is composed of three subatomic particles
o Protons
Indicate the element through atomic number
Atomic number indicates the number of protons
Symbolized with the letter (Z)
Reside in the nucleus of the atom
Relative charge is +1
Relative atomic mass unit is 1
o Neutrons
Do not have a charge

Document Summary

Chm233 lecture #1: chapter 1: remembering general chemistry electronic structure and bonding. Molecules of life are all carbon-based: such as proteins, carbohydrates, dna molecules and nucleic acids. Important to understand organic chemistry is due to the fact that most life molecules are carbon-based. Will focus on: structures and bonding, nomenclatures and functional groups, reactivity of organic molecules. Organic molecules contain a few types of elements: most important is carbon, nonmetals (right-hand side of the periodic table) Iodine: metals (most of the periodic table is of metals) Only when working with acid-base reactions due to transfer of ions. Columns represent groups aka families: main groups: 1a, 2a, 3a, 4a, 5a, 6a, 7a, and 8a, have similar behaviors and characteristics to one another. Rows represent periods: metals on the left, nonmetals on the right. An atom is composed of three subatomic particles: protons. Atomic number indicates the number of protons. Reside in the nucleus of the atom.
