Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield

Engineering Lecture : Mr: E Thorpe Title : Combustion The term complete combustion generally is used in connection with the burning of hydrocarbons. Combustion is the process of burning that occurs when fuel‚ oxygen‚ and heat are simultaneously present. The result of complete combustion is the release of energy‚ carbon dioxide‚ and water vapor. If the hydrocarbon contains sulfur‚ sulfur dioxide also will be present. On the flip side‚ incomplete combustion results in some of the carbon atoms combining

Cyclohexane is a saturated hydrocarbon and cyclohexene is an unsaturated hydrocarbon due to the presence of double bond.Both hydrocarbons produce carbon dioxide and water during combustion test. When the oxygen is limited‚ the product will be carbon monoxide and water. The alkenes are highly flammable and burn readily in air‚ forming carbon dioxide and water. In this experiment‚ the combustion of cyclohexene burns in an orange flame and produces relatively high amount of black soot. The black soot

BACKROUND INFORMATION Organic chemistry is the study of hydrocarbons and their various deviations. (Ex. natural gas‚ paper‚ proteins‚ carbohydrates) Saturated hydrocarbons are hydrocarbons with carbon-carbon single bonds. (Ex. C-C) Unsaturated hydrocarbons are hydrocarbons with one of more multiple carbon-carbon bonds. (Ex. C=C double bond‚ triple bond‚ or both) Stereoisomers have the same molecular and structural formulas but different orientations of atoms in space. Constitutional isomers

Exploring Boiling Points Introduction: Every substance has a unique set of properties that allow us to differentiate between them. These properties are classified as physical properties and chemical properties. Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color‚ odor‚ taste‚ density‚ melting point‚ boiling point‚ conductivity‚ and hardness. Chemical properties tell us how the substance

An examination of the porphyrin structure reveals that individual pyrrole units comprise the overall structure. As an aromatic compound‚ pyrrole can participate in electrophilic aromatic substitution reactions to form the porphyrin (your report should discuss the mechanism in great detail‚ including the regiochemistry). The initial porphyrinogen product is not fully aromatic‚ but oxidation from atmospheric oxygen in the presence of the Lewis acid silica gel allows formation of the fully conjugated
