2-methyl-2-butanol with HCl to form 2-chloro-2-methylbutane, and to understand Sn1 and Sn2 reactions, in terms of how they are different and why one is more likely to happen over the other. The OH group in 2-methl-2-butanol is attached to a tertiary Carbon, meaning the reaction should occur via Sn1, a two-step reaction, and Cl should replace the OH group, to form a tertiary halide. HCl was added to 2-methyl-2-butanol and then several extractions were done to purify the product. The percent…

Cyclohexene distillation A fraction containing primarily cyclohexene primarily cyclohexene and water is separated from raw cyclohexanone in Cyclohexene column. Raw Cyclohexanone is fed from storage tank to Cyclohexene Column via Cyclohexene heater. In Cyclohexene Heater, the feed is heated up to about 1200C with the heat carried by the bottom product from Alcohols column. The Cyclohexene column is operated at atmospheric pressure and temperatures of 850C at top and 1650C at bottom. The vapours…

In this study, we use the modified organo nanoclay as a new sorbent for separation and preconcentration trace amounts of Au(III) in aqueous solutions. Nanoclay was modified with 5-(4'-dimethylamino benzyliden)-rhodanine. Modified nanoclay was used as a solid sorbent for separation and preconcentration trace amounts of Au(III) ions. The sorption of gold ions was quantitative in pH range of 2.0 to 6.0, whereas quantitative desorption occurs instantaneously with 6.0 mL of 1.0 mol L-1 Na2S2O3. The…

The remaining acid chloride then reacts with diethylamine. Diethylamine is used in excess to neutralize the hydrogen chloride produced in the reaction. The lone pair of electrons on the nitrogen atom performs a nucleophilic attack on the carbonyl carbon, while a pair of electrons in the double bond is pushed to the oxygen atom. When an electron pair from the oxygen atom restores the double bond, the chloride ion will act as a leaving group. The nitrogen atom is deprotonated by a chloride atom,…

There is no mistaking the distinctive sound of a chainsaw, screaming as it bites through a hunk of wood or the bark of a tree. There are even chainsaws which are used to cut through concrete, brick and natural stone. Chainsaws are perhaps one of the most convenient power tools available, and can save a lot of time and effort in construction and felling. Although the origin of the chainsaw is debatable, it is determined that the first chainsaw was made around 1830 by Bernard Heine, a German…

panel. This panel stretches across a plain and gives enough power for almost all of Australia. The third one is Geothermal energy. This is when you mine into the ground and use the heat from the earth and tears it to energy. The next one is called Carbon Capture and Storage or CCS for short. This is when…

Carports are like the garage spaces you have in your houses. It functions the same way in giving protection to your cars. The only difference is that carports are not fixated. Instead, it is a portable and retractable device you can bring with you in your outdoor trips. The best carports for this generation are the ones made of metal, usually of aluminum or steel. There are also that has core panels made of insulated polystyrene foam. This is also wrapped with steel or aluminum. Most metal…

When it comes to towing, the B&W Tow & Stow Hitch offers different ball sizes without the need to change out the hitch anytime that you need to make a ball change. Additionally, it flips under the truck and hides out of sight when it is not in use. This hitch system is made to accommodate accessories like a draw bar for other towing needs. The draw bar makes it possible to connect other trailers that have pins or have tongues that cannot accommodate a ball. This draw bar is designed with a…

Draw resonance structures showing all the positions at which the positive charge is delocalized on the aromatic ring in the phenonium ion. If a methoxy group (-OCH3) or a nitro group (–NO2) were substituted in the 4-position on the aromatic ring, how would the stability of the phenonium ion change? Compare methoxy substituted, nitro substituted and unsubstituted, and order them by increasing stability. Explain your answer thoroughly. 2) Benzopinacol and benzopinacolone have nearly…

What can be done to protect yourself from toxic metal fumes during the welding process? It's been long known that not protecting yourself from such dangerous fumes comes at a very high price on your health. Acute and prolonged exposure may have very negative consequences. Fortunately there are many ways to protect your health and enjoy a prosperous long life. Without the proper protection, overexposure to hazardous fumes can show acute or chronic health effects. Acute effects appearing…
