Aldehyde and Ketone 1. ALDEHYDE Definition: An aldehyde is an organic compound containing a formyl group. This functional group‚ with the structure R-CHO‚ consists of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group‚ which is any generic alkyl or side chain. The group without R is called the aldehyde group or formyl group. Aldehydes differ from ketones in that the carbonyl is placed at the end of a carbon skeleton rather than between two carbon atoms

-1Determination of an Unknown Liquid (2-butanol) Through Fundamental Analysis Lee Billips Department of Chemistry‚ Shippensburg University‚ 1871 Old Main Drive. Shippensburg‚ PA‚ 17257. Abstract: The identification and characterization of unknowns are an important part of organic chemistry. It is fundamental to know experimental methods to deductively identify compounds (1) . The determination of unknown #6 (2-butanol) was identified by a series of test; first taking the boiling point (94-96

six-membered ring structures. The process of a DielsAlder reaction involves a substituted alkene reacting with a conjugated diene in the cis conformation to create two new carbon-carbon σ bonds which results in the formation of a six-membered ring‚ as shown below: Figure 1: Example Diels-Alder reaction + 1‚3-butadiene ethene cyclohexene In the case of the reaction outlined in this report‚ the substituted alkene is maleic anhydride‚ and the conjugated diene is cyclopentadiene. The two undergo

Chirality of Ethyl-3-hydroxybutanoate Generated from a Biological Pathway Jake Zimny LaSalle University Philadelphia‚ PA 19141 Submitted February 10‚ 2006 Abstract: The reaction being studied is a reduction of a ketone into an alcohol with a chiral center. Because a biological agent‚ bakers ’ yeast‚ is being used to drive this reaction‚ the optical purity that results in the product is so stereo-selective that the major product‚ (+)‚ is formed for 89% of the product.

cyclo-alcohol to become a cyclo-ene. In this case 4-methylcyclohexanol was protonated using phosphoric acid to become 4-methylcyclohexene. This demonstrates the loss of an alcohol group by protonation‚ the loss of a proton from the cyclohexane to form an alkene through elimination. This also demonstrates Le Chatelier’s principle‚ by using distillation to remove the product as it is formed the equilibrium of the reaction will constantly be in favor of the product.

Cyclic dienes added to alkene dienophiles also lead to two new form of stereoisomeric products‚ the endo and exo products (Kilway‚ “Lecture”). In cases where dienes and dienophiles align above one another‚ the endo product is formed (Hunt). The endo product will have two axial substituent groups (Kilway‚ “Lecture”). This formation typically forms the major product because it takes less kinetic energy to be formed due to secondary orbital interactions with the substituents in transition states (Hunt)
