20a. Bond Markets
Bonds are notes payable (notes that will be repaid in the future or rather at its maturity) that bear interest during the life of the bond. Typically, bonds are viewed to be safe investments because of its predictable and steady stream of payments (interest). The key difference between stocks and bonds is that when stock is purchased, the stockholder is receiving a percentage of the company they have invested in. In other words, stockholders, depending on the proportion of…
Required Knowledge (Preliminary Course)
Energy from Fossil Fuels
Originates from sun - solar to chemical by photosynthesis.
Red and violet wavelengths of sunlight absorbed by pigment chlorophyll, energy converted to chemical energy in glucose.
Glucose – carbohydrate: high-energy compound of C, H and O.
6CO2(g) + 6H2O(l) + energy C6H12O6(aq) + 6O2(g)
Petroleum consists of cruide oil and natural gas, formed of remains of single-celled marine organisms.
Quick burial, decay by bacteria…
Unit Two: Atoms
● 400 B.C.- billiard ball shaped
○ Asked: Could matter be divided into smaller and smaller pieces forever
or is there a limit?
○ Theory: Matter couldn’t be divided any smaller, eventually the smallest
piece possible will be achieved
○ “Atomos” - Smallest piece
○ Atoms are infinite in number
○ His theory was ignored for nearly 2000 years
○ All elements are composed of atoms. Atoms are indivisible and
○ Atoms of the same element…

Chem 220 Notes
Ch. 01 and 02: Structure and Bonding of Organic Molecules
I. Types of Chemical Bonds
A. Why do atoms forms bonds?
Atoms want to have the same number of electrons as the nearest noble gas atom (noble
gas configuration). This requires having a completely full or completely empty valence
shell of electrons.
Most main groups atoms will try to have eight valence electrons to completely fill their
valence shell; this is the octet rule. There are some exceptions: hydrogen…
On December 20, 2002, the Company filed a lawsuit (The Coca-Cola Company v. Aqua-Chem, Inc., Civil Action No. 2002CV631-50) in the Superior Court of Fulton County, Georgia (the ‘‘Georgia Case’’), seeking a declaratory judgment that the Company has no obligation to its former subsidiary, Aqua-Chem, Inc., now known as Cleaver-Brooks, Inc. (‘‘Aqua-Chem’’), for any past, present or future liabilities or expenses in connection with…
Chemistry and Structure Activity
Relationships for Tetrahydrocannabinols
R. K. Razdan
n overview is presented of the chemistry and the known structure activity relationships
(SAR) for tetrahydrocannabinols (THCs), endocannabinoids and pyrazole based an
tagonists. An attempt has been made to highlight and put in perspective the cannabinoid work carried out before and after the discovery of the receptors. In the cannabinoid…

This is a test of your knowledge of chemistry. Use that knowledge to answer all
questions in this examination. Some questions may require the use of the Reference
Tables for Physical Setting/Chemistry. You are to answer all questions in all parts of
this examination according to the directions provided in the examination booklet.
1.1 Ambient mass spectrometry
Mass spectrometry is an essential analytical tool in chemistry, biochemistry, pharmacy, medicine and many other related sciences. It is used in structural elucidation of unknown compounds using m/z ratio of fragmented ions. . ‘Ambient mass spectrometry’ allows direct analysis of samples in their native state in an open air environment. This leads to generation of ions and neutrals outside the vacuum system allowing unique experiments to be…
isomerism etc. (see CH160 lecture notes). Linkage isomers arise because
some ligands can bond via one donor atom in one compound, but via a different atom of the same ligand in another
compound. Typical examples of linkage isomersism are:
NO2– M-NO2 nitrito-κN (formerly nitro) M-ONO nitrito-κO (formerly nitrito)
CN– M-CN cyanido-κC (formerly cyano) M-NC cyanido-κN (formerly isocyano)
NCS M-SCN thiocyanato-κS (thiocyanato) M-NCS thiocyanato-κN (isothiocyanato)
(Note the old names are given for some…
