Organic Chemistry

Organic Chemistry is the examination of the structures and behaviors of carbon-based compounds. It uses both physical and chemical methods to evaluate these properties. Although it aims to study the behavior of organic substances in its purest form, it also focuses largely on organic reactions within different chemical systems, such as in solutions and mixtures. Even though Organic Chemistry is considered an isolated sub-discipline of chemistry, it is not truly distinct from Inorganic Chemistry, Physical Chemistry or General Chemistry, as it draws on concepts from each of these disciplines.

Organic Chemistry largely focuses on the study of structure, as one of the underlying principles is that structure determines behavior. Thus, by knowing an organic compounds structure, a chemist can predict its behavior under different chemical contexts. A common way to determine structure is through spectroscopy, which is the study of the electromagnetic interactions within the molecule under study. For example, analyzing the different peaks in a mass spectrum will reveal the mass-to-charge ratio and abundance of the different ions that are generated using the mass spectrometer. Thus, using analytical techniques to determine structure, property or reactivity is extremely important in the field of Organic Chemistry.

Since organic compounds form the basis of all life on Earth, the applicability of Organic chemistry is not limited to the laboratory – it also heavily extends into the fields of industry, agriculture, medicine and even botany. Thus, studying Organic Chemistry is essential for the prediction of organic chemical behavior.

Chemiluminescence Lab Questions

Intent of lab: To synthesize 1,2-dioxetanedione which reacts with a polyaromatic molecule to produce light. 0.37g sodium percarbonate (containing 0.0035 mol H2O2) is added to test tube with 1mL of prepared (COCl)2 solution in it. (Note: in 10mL of prepared (COCl)2 solution there is 0.4mL (COCl)2 in 9.6mL CH2Cl2). 5 test tubes a

Synthetic questions - phosphonate

So in the problem it says the phosphonate will be helpful. From what I could gather they would be attacked by making the bromine into a grignard and the left side of product isn't hard to accomplish but getting rid of the ester on the right to give the doubly a-b unsaturated ketone is where I am not getting it. I assume that's

Synthetic questions

I cant figure out these two problems to save my life, for the first one I have researched my notes & papers to selectively add a methyl and alcohol trans across an olefin. If I try to oxidize the alcohol to get an alpha-beta unsaturated ketone to do 1,4 reactions none will get me the alcohol in the alpha position unless when fo

Recrystallization

The goal of the recrystallization procedure is to obtain purified material with a maximum recovery. For each of the following situations, explain why this goal would be adversely affected. a) In the solution step, an unnecessarily large volume of solvent is used. b) The crystals obtained after filtration are not washed with
