Traditional deffintion of organic chemistry Chemistry of compounds found in living species (organisms) Modern deffiniton of organic chemistry Study of carbon compounds (just because it contains carbon doesn’t make in organic
Torbern Bergman (1770) expressed the difference between organic and inorganic
(living v. nonliving) Antoine Lavoisier (1780’s) first table of elements, organic always contains C, usually H, often O & N
Michel Chevreal (1816) converted one organic compound into another then seprated into pure organic compounds (fattyacids) huge blow to vital force theory Friedrich Wohler (1828) converted inorganic compound (ammonium cyanate) into organic compound (urea)
Proton P+ , +1
Located in nucleus
Mass about 1
P=N Neutron No , 0
In nucleus
About one
Electron e-, -1 outside nucleus about 0 Atomic number (Z) # of protons
Mass Number (A) # of protons + # of neutrons Isotope Atom of the same element with same Z and different A
Atomic weight Weighted atomic mass of all “stable” isotopes of an element Orbital Solution to wave equation (wave function) and home of electrons
Wave function Predicts the volume of space about a nucleus that has a 95% probability of finding an electron w/ certian energy Wave equation Mathematical discription of an electrons motion around a nucleus according to quantum mechanical model
Various orbital names S, P, D, F……. ect S 1 lobe
1 orbital at each E level
2 e- at each E level
P 2 lobes
3 orbital at each E level
6 e- at each E level D 4 lobes
5 orbital at each E level
10 e- at each E level
Shells Different layers about the nucleus in which electrons exist Node Region of 0% electron density
# nodes = (n-1)
Different shells have: Different distances from the nucleus, energy levels, number and kind of electron orbital, # of nodes Autbau principle e- fill lowest energy levels first
Pauli exclusion principle Max of 2e- can occupy each orbital and must be opposite spin Hunds rule If more then 2 orbitals of equivalent value exist then each orbital is half filled, if not enough e-
August Kekula and Archibald couper (1858) indepedantly proposed that C has 4 affinity units in all organic compounds. Tetravalent, Kekula C can bond to form extend chains of atoms
Emil Erlenmyer Proposed C-C triple bond A. Crum Browm Proposed C-C double bond
Van’t Hoff and Le Bel (1874) Proposed 4 bonds of C are not randomly orienated, have specific special direction Van’t Hoff C with 4 attached atoms is tetrahedral in nature
Ionic bonds Metals/nonmetals
Transferral of electrons from metal to nonmetal Covalent bonds Nonmetal/nonmetal
Due to sharing of electrons
Metallic bonding Metals/metals Valence shell An atoms outermost electron

preparatory courses should be completed prior to transfer. At minimum, you should complete one year of biology with laboratory, one year of general chemistry with laboratory, one year of calculus and one semester of organic chemistry with laboratory. Completion of a second semester of organic chemistry or one year of calculus-based physics is strongly recommended. Also, completion of one statistics course prior to transfer is recommended as preparation for upper division work in the major. For more information…

Chem 220 Notes Page 1 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…

Chapter 1 1. Introduction: 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…

Pharmacy Vs Registered Nurse

get into pharmacy school have an undergrad degree in chemistry, biology, etc.. Pharmacy school is getting very competitive and it will not be long until an undergrad degree will be required! I don't think for a nursing program you have to take organic chem, physics, and calculus. The salary for a pharmacist is more than a nurse. I think it depends on where you work and how much you work. Pharmacist make 90 to 120 depending on where you work. Nurses's can make a lot more than that but again I think…
