Exercise 5 Comparing the Reaction Rates of Alkanes and Alkenes Group # 4 Members: Pangan‚ Sam Margarette Perales‚ Angelica Ibay‚ Sophia Irigan‚ Sharien May Sorensen‚ John Antonio Ocan‚ Emmanuel Submitted to: Ms. Ginalyn Cuenca Mr. Neil Abreo Date: December 6‚ 2012 Introduction Alkanes are hydrocarbons with only single bonds between the atoms. Saturated hydrocarbon is the other term for it. They are used as fuels because they are non-reactive and also do not conduct electricity

Experiment #3 Mark A. Bruder 07. T.A. Michael Hall Alkanes: Chlorination Introduction: The purpose of this experiment is to determine the reactivity of hydrogen atoms on a carbon chain using free radical chlorination. In this experiment 1-chlorobutane will be chlorinated with the combination of sulfuryl chloride and ABCN as an initiator to produce the chlorine radicals. The combination of 1-chlorobutane and sulfur chloride will produce four dichlorobutane

Alkanes The reaction between alkanes and fluorine This reaction is explosive even in the cold and dark‚ and you tend to get carbon and hydrogen fluoride produced. It is of no particular interest. For example: The reaction between alkanes and iodine Iodine doesn’t react with the alkanes to any extent - at least‚ under normal lab conditions. The reactions between alkanes and chlorine or bromine There is no reaction in the dark. In the presence of a flame‚ the reactions are

Alkanes This is the correct chemical term for compounds known as paraffins. They are considered the simplest organic compounds and are a family of chain hydrocarbons having the general formula C2H2n+2. All of the bonds are single bonds (-C-H-‚ and -C-C-). The chains can be straight or branched. The smaller members (less than 4 carbons) are gases‚ while larger ones (five to seventeen carbons) are liquids. Beyond seventeen carbons the alkanes are waxy solids. Structure: The simplest saturated acyclic

used and extracted‚ we could run out of oil in 50 years. We need to conserve what fuels we have left and stop using them in our cars. Another big problem with burning fossil fuels‚ especially gasoline‚ is the damage it causes to the environment. Combustion of fuels in cars has been identified as the largest contributor to air pollution in the world.

Comparing alkanes and alkenes Aim: Is cyclohexane more or less reactive than cyclohexene in the presence or absence of light Hypothesis The cyclohexene will reactive the fastest because being an "ene" it has a electron rich area making it more reactive than cyclohexane but neither one of the will react without light Materials * 4x 250ml conical flasks * 2 rubber stoppers * Aluminium foil * Cyclohexane * Cyclohexene * Bromide water * Measuring cylinder

For ex. Wood ‚paper 3 FUEL: A substance that is burnt for obtaining heat and light is called a fuel.

Professor Department of Aerospace Engineering IIT Kanpur 13th July‚ 2012 ABSTRACT Numerical Studies of Microcombustion in a Micro-channel There are a lot of methods that converts chemical energy to thermal energy like fuel cells. But combustion is the most important one to obtain thermal energy from various fuels including hydrogen‚ natural gas‚ fuel oils because of its more energy output. Microcombustion is a potential energy source for small devices like unmanned vehicles and micro
