Sabah Comparing Reactivity Of Alkanes and Alkenes Aim: To compare the reactivity of an alkane and an alkene Hypothesis: The cyclohexene would react to the bromine water and turn colourless‚ whilst the cyclohexane won’t react. Risk Assessment: What’s the problem? | How do you fix? | How does it work? | Bromine water is corrosive to the skin | Wear gloves | Stops the Bromine water from reaching skin | Cyclohexane/ene is highly flammable | Keep away from naked flames. | No naked flame = no ignition

Bromination of Trans-Cinnamic Acid Christopher B. Martin CHEM 3411 1 Mechanism of Bromine Addition to Alkenes Understanding the chemical mechanism (order of bonds broken and made as well as intermediates formed) has a great value in chemical synthesis. The chemical mechanism of a reaction will influence the rate of the reaction‚ the stereochemistry of the product(s)‚ and the extent of possible undesired side reactions. Organic reaction mechanisms investigate the path towards a desired product

presence in an organic molecule. 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

Alcohol should be banned from public events What if you were told that mortality in Canada could be reduced by as low as 3000 a year! Would you be willing to accept the terms in order to make this happen? According to Parliament of Canada‚ statics by Collin (2006) reveals “1‚055 person died in alcohol-related road crashes in Canada in 2002” and “666 people died as a result of mental and behavioral disorders due to the use of alcohol.”‚ making alcohol consumption a known risk factor for mortality

from The Emigrants by Edward Kamau Brathwaite The poem from The Emigrants by Edward Kamau Brathwaite is the thoughts of an indigenous inhabitant‚ the persona‚ thinking of the invasion that has been so abruptly brought upon them which they must now face. We know that the persona is one of the inhabitants because in line four and twelve‚ the repetition of “my” personalizes what is happening‚ coming from an inhabitant’s perspective. The themes perception versus reality‚ power‚ discovery and war

Old Dominion University ORGANIC 214 Alkene Addition Submitted by: Alkene addition: Bromination of (E) Stilbene Introduction: In this lab we used the greener approach‚ which involves the addition of bromine across a double bond. When bromine reacts with E-stilbene (trans-1‚2-diphenylethene)‚ two new chiral carbons are created from the sp2 carbons‚ therefore 3 different dibrominated stereoisomers are possible: meso-(1R‚2S)‚ or the raceminc mixture-(1R‚2R) or (1S‚2S)-dibromo-1‚2-diphenylethane

Dehydration of Alcohols Abstract The dehydration of cyclohexanol to cyclohexene can be done through fractional distillation. Once the fraction has been collected it must then be dried. The dried distillate is finally tested to determine whether or not it has been dehydrated. The three tests used were infrared spectroscopy‚ Bromine chemical test and Bayer’s chemical test. The infrared spectroscopy showed a large narrow peak at 3062.12(cm-1) and 3020.71(cm-1) which indicates that there is a double

They also said that a student must havea special place to study with plenty of room to work. And students should notbe cramped. They presupposes that study time will go better if a learner takea few minutes at the start to straighten things up. A desk and straight-backedchair is usually
