Alkene Synthesis from Alcohol: Preparation of Cyclohexene From Cyclohexanol 5/29/14 Abstract: A 42.89% yield cyclohexene was successfully synthesized from 10.0 mL cyclohexanol by unimolecular elimination (E1) through the dehydration of cyclohexanol and confirmed via a bromine test and the IR spectra. Introduction: Alkenes are hydrocarbons that have carbon–carbon double bonds and are one of the many functional groups in organic molecules. Alkenes are sp2 hybridized

Sexual Addition may be a common problem but it still remains a relatively understood condition characterized by strong sexual urges. In recent weeks‚ the issue has resurfaced. Last week‚ a Journalist Brian Alexander(2007)‚ this psychological condition was once again questioned and the condition was described as such: "Sexual addiction is defined as any sexually-related‚ compulsive behavior which interferes with normal living and causes severe stress on family‚ friends‚ loved ones and one’s work

free-radical chain bromination‚ we were expected to be able to determine the relative reactivates of the many types of hydrogen atoms involved toward bromine atoms. Bromination is defined to be a regioselective reaction meaning bromine has preference of making or breaking a bond over all other directions that it may have had available. In this case‚ Markovnikov’s rule is revealed to be the case in this situation that states that adding a protic acid represented as HX to an alkene (sp2 hybridized)‚

Name _____________________ Class ______________ Date _________ Addition and Resolution of Vectors Equilibrium of a Particle Overview When a set of forces act on an object in such a way that the lines of action of the forces pass through a common point‚ the forces are described as concurrent forces. When these forces lie in the same geometric plane‚ the forces are also described as coplanar forces. A single G G equivalent force known as the resultant force FR may replace a set of concurrent forces

Addiction as Choice? Andria Burgess Introduction to Psychology Addiction as Choice? Substance abuse is a pervasive problem throughout the United States. It affects all populations‚ socioeconomic groups‚ ages‚ and races. Within the community of substance abuse treatment providers‚ there is an ongoing debate on whether addiction is a disease‚ or whether individuals who abuse substances choose to engage in the behavior. There is evidence to support both positions. This paper will examine

al Chain Reactions: Bromination of Arenes Introduction The purpose of the bromination of arenes was to determine the different reactivities of different hydrocarbons with different hydrogen atoms when reacted with bromine under free-radical substitution. The time it took for the bromine color to disappear was used to determine the order of reactivity of the different hydrocarbons. Data and Results The data of the 10 hydrocarbon tubes and the 2 control tubes with bromine and dichloromethane in

LAB REPORT! EXPERIMENT#5‚6! MANPREET KAUR KHAIRA! LAB PARTNER: VIAN RAIES! The purpose of this lab exercise was to perform the bromination of (E)-1‚2-diphenylethene (trans-stilbene) by addition reaction in which bromine was added across the double bond to yield a vicinal dibromide. The next step was to perform a double elimination reaction by product gained to synthesize an alkyne‚ that is‚ 1‚2-diphenylacetylene. The two major techniques used in this lab were TLC analysis and UV-vis spectroscopy

Common functional groups found in organic molecules are listed below: * Alkene * Primary alcohol * Tertiary alcohol * Aldehyde * Ketone * Carboxylic acid * Ester * Halogen alkane * Phenol Alkene In organic chemistry‚ an alkene is an unsaturated chemical compound. This means it contains a carbon – carbon bond. All alkenes are hydrocarbons‚ (a molecule made of carbon and hydrogen atoms)‚ and can only form one double bond which must

is a relationship between addition and multiplication. When you are multiplying you are simply adding the same number several times. For example 2*3 is the same as adding 2 three times‚ 2*3=6 which is the same as 2+2+2=6. Understanding the relationship between addition and multiplication contributes to the understanding of these concepts to the student because the student will be able to grasp the concept with more ease since they should have been experts in addition once they start learning multiplication
