connected by bonds that resonatebetween single and double bonds; each carbon is also bound to a single atom. Benzene isinsoluble in water but mixes in all proportions with organic . Benzene is itself an excellentsolvent for certain and for most simple organic chemicals. It is one of the most commonly used solvents in the organic chemical laboratory. If inhaled in large quantities‚ benzene is poisonous. The vapors are explosive andthe liquid violently flammable. Many compounds are obtained from

to the origin of life‚ there is a schism over whether proteins of living cells or the genetic information was a precursor to the other. These debates have raised key questions over which conditions most favored the emergence of life. The myriad of organic life on the Earth may be derived from a number of sources: oceanic based genetic synthesis‚ volcanic-oceanic based metabolic synthesis‚ and interplanetary meteorites. Limitations of physical and experimental evidence has left this debate in much flux

using the acid-catalyzed isomerisation‚ vacuum filtration‚ and reflux processes. The second part of the experiment was intended for using the molecular modelling kits as a way to visualize the differences between such isomers. Discussion: Organic compounds and their three-dimensional shapes can be represented through diagrams. Two particular methods of illustrations are the sawhorse representation and the Newman projection. An example of both these methods is seen in figure 1. (1) |

Paige Morgan. Edvard and Paige first meet at a bar where Paige works‚ their first meeting doesn’t go well though(oh I thought first impressions matter). The first day of classes they discover that they are classmates‚ seatmates and partners in organic chemistry class. They don’t go along for quite sometime until Paige teaches Edvard how to do the laundry and Edvard in return helps her with Shakespeare‚ this leads Paige to invite Evdard to spend the sem break (thanksgiving) at her farm. Here Edvard joins

"warm little pond" of organic chemicals that‚ over a long period of time‚ gave life to the first organisms. As this theory evolved‚ the pond became an ocean. In a breakthrough experiment conducted by Stanley Miller in 1953‚ the first reasonable experimental evidence for Darwin’s theory was developed. This evidence lay in a glass jar‚ in which a simplified version of earth in its infancy was created. Using water‚ ammonia‚ hydrogen and electrical discharge‚ Miller created organic chemicals‚ including

Pre-Lab: Analgesic drugs are known for reducing pain‚ while antiseptic drugs reduce symptoms such as fevers and swelling. However‚ some of these drugs can reduce both illnesses. To obtain a pure compound in these drugs‚ the scientist needs to separate the desired compound by taking advantage of the different physical and chemical properties. Such as; different boiling points

Basic principles [edit] In chemistry‚ a number of prefixes‚ suffixes and infixes are used to describe the type and position of functional groups in the compound. The steps to naming an organic compound are: 1. Identification of the parent hydrocarbon chain. This chain must obey the following rules‚ in order of precedence: 1. It should have the maximum number of substituents of the suffix functional group. By suffix‚ it is meant that the parent functional group should have a suffix
