Abstract The aliphatic and aromatic hydrocarbon are can be differentiate by .For example‚in the experiment involving aliphatic hydrocarbon which is cyclohexane that undergo the reaction with bromine water in the presence of UV light.This reaction is known as substitution reaction.The cyclohexane that react with bromine under present of UV light will change to slightly brown while the other one has no changeous which is still brown.For baeyer’s test‚the alkane which is heptanes will not undergo the oxidation

How many electrons do these elements have in their outer orbit? b) Bromine has the same chemical behaviour as chlorine and fluorine. Where is bromine found on the periodic table in relation to chlorine and fluorine? c) How many electrons do you suppose that bromine has in its outer orbit? 5a) Helium‚ neon‚ and argon behave similarly in chemical reactions. What do you notice about the outer orbit of electrons in

What is gel electrophoresis? Gel electrophoresis is a technique that separates pieces of DNA (or other biological molecules) by size. Pieces of DNA in a test tube all look the same. DNA Gel Electrophoresis Gel electrophoresis separates pieces of DNA by size so that researchers can further analyze them BURST Training Session November 29‚ 2005 Once the DNA samples are loaded onto the gel‚ an electric current is applied to the gel. DNA is negatively charged due to all the phosphate groups in the

Chapter 1: Introduction Chapter 1: Introduction Ionic liquids (ILs) can be viewed as a new and remarkable class of solvent. They are also a type of materials that have a long and useful history‚ where the earliest material that meets the current definition of IL was observed in the mid-19th century when a separate liquid phase called the “red oil” was observed in Friedel-Crafts reaction [17]. Over the following years‚ there has been a rapid growing of interest in ILs due to the realization

Lab 3: Grignard Synthesis Objective: The goal of this lab is to synthesize a Grignard reagent from bromobenzene and magnesium metal in diethyl ether. This same Grignard reagent would then be used to prepare a tertiary alcohol and then purify and characterize the product.

Chemistry A Bonding Worksheet #1: Introduction to Ionic Bonds The forces that hold matter together are called chemical bonds. There are four major types of bonds. We need to learn in detail about these bonds and how they influence the properties of matter. The four major types of bonds are: I. Ionic Bonds III. Metallic Bonds II. Covalent Bonds IV. Intermolecular (van der Waals) forces Ionic Bonds The ionic bond is formed by the attraction between oppositely charged ions.
