Preparation of 4-bromoaniline Introduction Aromatic compounds tend to undergo electrophilic aromatic substitutions rather than addition reactions. Substitution of a new group for a hydrogen atom takes place via a resonance-stabilized carbocation. As the benzene ring is quite electron-rich‚ it almost always behaves as a nucleophile in a reaction which means the substitution on benzene occurs by the addition of an electrophile. Substituted benzenes tend to react at predictable positions. Alkyl groups

9405 = 24% In this example‚ the lender stated a simple interest rate of 10 percent. Yet you actually are paying an effective APR of 24 percent once you add in the fees and you do not have the use of the full loan for the entire loan period. 3. Compound interest arises when interest is added to the principal so that from that moment on‚ the interest that has been added also itself earns interest. This addition of interest to the principal is called compounding. The following formula gives you

Aim: to perform a firsthand investigation to compare the physical and chemical properties of magnesium and oxygen when they are experimented to form magnesium oxide Theory: The empirical formula of a compound is the formula that tells us the ratio in which the atoms are present in the compound. To calculate an empirical formula: - Write down the masses of all of the elements present - Convert masses to moles (by dividing by atomic weights in grams) - Divide through by the smallest number of

(70 points) Title | How the Volume of the Slurry Mix Effected the Biogas Generator | Type of Experiment | Experimental | Background Information | Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane‚ the main component of natural gas‚ and probably the most abundant organic compound on earth. For this experiment we had created a bio gas generator. A biogas generator is any gas fuel derived from the decay of organic matter‚ as the mixture of methane and carbon

models of elements‚ compounds‚ and mixtures. The lab asks you to examine conceptual models of matter in which atoms of one element are represented by nuts while atoms of another element are represented by bolts. After examining each model‚ complete the following tasks: a. sketch a representative molecular picture of the model; b. describe the composition of the model in words (does the model contain atoms‚ molecules‚ or both?; does the model represent elements‚ compounds‚ or both?; does the

Water and me Water is a colourless‚ transparent and odourless liquid which forms the seas‚ lakes‚ rivers‚ and rain and is the basis of the fluids of living organisms. It is a chemical compound whose formula is H2O. It covers 71% of the earth’s surface and is necessary for every known organism to live. 97% of the total water found on the earth lies in the oceans. The rest of water is in the form of glaciers and ice caps (2.1%)‚ ground water (0.6%)‚ inland water (0.2%) and water vapours (0.001%).

electrophilic reaction is when the pi bond of a molecule is removed to make two covalent bonds that are bonded to two new molecules. A nucleophillic addition is a reaction that removed the pi bond from a molecule and adds covalent bonds with two new compounds. Halogenation or most commonly known as bromination is a reaction that breaks a pi bond and adds a halogen or in this case‚ a bromine to the molecule. This addition of the bromine can be very steroselective. Stereoselectivity can come from

Background Information: There are many ionic compounds that contain one or more waters of hydration in their formulae. They exists either in anhydrous or hydrated form. Most anhydrous compounds have a strong tendency to absorb water from the humidity in the atmosphere and shifts into a hydrated form. Because of that phenomenon‚ those compounds are used to reduce moisture in places where water moisture can damage certain products. The anhydrous compounds are separated into three categories: hygroscopic
