Prelaboratory assignment Examples of questions related to the Dumas method: How many grams of ethanol would occupy 750 mL at 790.5 torr pressure at 100oC? (molar mass of ethanol is 46.0 g mol-1) Relavent equations: PV = nRT 1 atm = 101.3 kPa R = 0.8206 L atm mol-1 K-1 P = (750 torr)(1atm/760 torr)…

The hydro-ecosphere provides a more favorable environment for microorganisms compared to the atmosphere and lithosphere due to the presence of water. Water plays a crucial role in microbial metabolism (Atlas and Bartha, 1993). The unique properties of water also make it suitable as a habitat within the hydrosphere.

Abstract Benzene and benzene derivatives undergo electrophilic substitution rather than addition to maintain their aromaticity. In the nitration of benzene, anhydrous nitric acid reacts with sulphuric acid as a catalyst to form an electrophile which then attacks the benzene and attaches to it. Chlorine is an example of an ortho-para director and nitration of 1,4-dichlorobenzene…

No direct synthesis of safrole has been recorded. The most recent attempt was made by Baker and Robinson (JCS, 1925, 127, 1424). They distilled the product of the action of silver oxide and water upon gamma-piperonylpropyltrimethylammonium iodide, but ended up obtaining isosafrole instead. In isosafrole, the double bond moves into the position of greater stability….
