Periodic Table The periodic table is a table‚ where all known chemical elements are arranged. They are organized on the basis of their atomic numbers‚ electrons and chemical properties. The atomic of an element is the same as the number of electrons or protons in that particular atom. They elements in the table are placed in order from the lowest to the highest. 429768018669000The periodic table is ordered into periods and groups. A row of elements across the periodic table is calleda a period

The Cyclohexanol Cycle and Nylon Synthesis Samantha Stuckey CHE 233L Section 302 Department of Chemistry‚ DePaul University‚ 1110 W. Belden Avenue‚ Chicago‚ IL 60614 smstuckey@comcast.net May 8th‚ 2013 Abstract The first three labs of this organic chemistry experiment involved carrying out the first three parts of the Cyclohexanol Cycle. The cyclohexanol was first converted to cyclohexene and water by simple distillation (product: 6.5395g‚ 79.75% recovery). The cyclohexene then underwent a bromination

You are probably wondering what this table of colourful boxes is? Well you’ve come to the right place‚ I hope. What is it? Well everything in the world is made up of elements‚ well almost everything‚ light‚ heat‚ this is energy‚ another story. And elements are a single type of atom‚ the periodic table is basically a table of all know elements to man. What’s in it? To understand what’s in it we need to look at an atom and it subatomic parts. An atom is made up of an Electron(e-) this has a negative

Going back to our reaction mechanisms‚ we were looking at SN1 and SN2 reactions‚ so we of course used the hydrobromic acid as our acid catalyst which would be protonating the hydroxyl group of our butanol‚ to make a better leaving group‚ so that the bromine radical would be able to attack the leftover carbocation. Our group used 2-bromobutanol and we expected‚ from our mechanism‚ to achieve 2-bromobutane and when we compared our GC results to the prepared sample‚ our mechanism proved to be true. We did

In order to first perform the reaction‚ 1.5 mL of 4-methylcyclohexanol was added to a pre-weighed 5mL conical vial. The conical vial was then weighed to find the actual mass of 4-methylcycloheaxanol. Then‚ 0.4mL of 85% phosphoric acid was added to the conical vial using a plastic pipet. Six drops of concentrated sulfuric acid was then added to the vial using a glass pipet. A spin vane was then added before adding the Hickman head‚ water condenser and a drying tube packed with calcium chloride to
