This on-line reaction index allows searching for reactants, products, conditions, and comments. Book references are given for Organic Chemistry, Third Edition by Paula Jurkanis Bruice and for Organic Chemistry, Fourth Edition by L. G. Wade, Jr. (work in progress) It can produce more than a mole of quizzes.
This on-line reaction quiz accompanies the Reaction Finder, but presents the quiz questions in a slightly different form.
This absolutely beautiful introduction to organic chemistry by Bill Reusch at Michigan State University is a MUST SEE, MUST DO. It includes very well organized discussions, quizzes, and visualizations of all of the important topics in introductory organic chemistry. WOW!
A simple model kit for under $15 is Kit #3.
Perhaps hard to believe, but draw an organic structure, and this server will calculate an IUPAC systematic name for it. I kid you not!!
This site does the opposite: Write simple IUPAC names, click to display the structure (based on SMILES).
Hypertext linked rules for naming organic compounds. Includes several examples for each rule.
A list of sites which discuss the nomenclature of organic compounds.
A random assortment of alkanes to name.
Compare two alkane structures. Are they the same? Can you name them? Click 'Analyze' to find out.
Just a short one-page summary of alkane naming.
How to identify R vs. S isomers at a glance using the "drive-the-car" analogy.
Practice naming aromatic compounds.
"The summaries and quizzes which can be selected are designed to assist organic chemistry students in the review of the basic reactions; they are similar to the summaries in the text and include references to it. We have chosen to use specific examples, rather than R-group notation, so that you will see the reactions in context in a real, but simple, molecule."
A huge list of named reactions in alphabetical order hypertext linked to drawings and references.
Practice determining the site of electrophilic aromatic substitution.
Practice your syntheses! Select or draw a reactant and a product. If it can be done in five steps or less, this calculator will probably figure it out.
Chime animation created by morphing distinct CAChe conformations of cyclohexane. Each named conformation can be looked at and manipulated.
Chime, Rasmol, and site links relating to the display of molecules.
SHMO is an interactive program to perform electronic structure calculations within the "Simple Huckel Molecular Orbital" approximations. Click to add atoms and bonds. The orbital energy diagram is generated automatically. Click on an energy level and see the top view of the pi molecular orbitals. Cool! (Internet Explorer users may need to update their Java VM)
HMO-plus 2.0.3 executes molecular orbital calculations on the Macintosh computer for structures containing up to one hundred atoms. A number if different types of molecular orbital calculations can be performed; these include simple Hueckel, omega-technique, improved two parameter omega-technique (ITPOT), and SCF (Pariser-Parr-Pople approximation) calculations. The program is highly interactive and simply requires that the structure of a target molecule be drawn with the mouse by selecting any desired rings or heteroatoms from a palette. The program automatically constructs the secular determinant from the supplied structure and computes the eigenvectors and eigenvalues by the Jacobi diagonalisation method. The output of the program can be displayed in both graphic and tabular form and includes the empirical formula, number of atoms, number of pi-electrons, secular determinant, eigenvalues, total energy, delocalization energy, delocalization energy per pi-electron, eigenvectors, charge densities, dipole moment, total charge, electron density-bond order matrix, electrophilic, radical, and nucleophilic superdelocalizabilities, mutual and self-atom polarizabilities, and freevalences. The program also displays a color diagram of the pi-electrostatic potential. This newest version of the program displays color diagrams of the molecular orbitals, the atom-centered, bond-centered, or total pi-electron populations, and a pi-electron density difference map that are constructed using STOs. Full documentation and some sample calculations are included.
