1. To pass Chem 18.1, ELIBAP must be able to determine the melting points of three ester compoundsextracted and purified from three different plants.Ester 1Ester 2Ester 3:0:H.MW: 182.17 g/molMW: 152.15 g/molMW: 164.20 g/molPossible Melting Points:-31 °C64-67 °C-9 °Ca. Given the molar mass and molecular structures of the esters, determine their most possiblemelting points.b. According to her friend who took Chem 18.1 last semester, one of the ester compounds existsas a solid above room temperature (25 °C) while the rest remain in their liquid forms. Identify theester which is present in solid form above room temperature. Draw the structure.

Melting point is temperature at which the phase of the substance changes from solid to liquid. For…

Waste vegetable oil (WVO; e. g. spent deep fryer oil) is often used to produce biodiesel. WVO tends to have relatively high amounts of free fatty acids (FFA) compared to unused vegetable oil. For a base catalyzed process, why might the presence of FFA cause problems? Provide a reaction scheme in your explanation.

The boiling points for the compounds are 118 °C and 35 °C respectively. The solubility for both compounds is the same (8g/100g water). Explain this observation for (i) boiling point disparity; (ii) solubility similarity H-bonds form in diethyl ether; n-butyl alcohol forms H-bonds in water H-bonds form in n-butyl alcohol; diethyl ether forms H-bonds in water H-bonds in n-butyl alcohol; Both compounds form H-bonds in water O Both compounds form H-bonds; Both compounds form H-bonds in water

Another source of phosphorus in water is known as organic phosphorus which commonly finds its way into natural bodies of water from human and animal waste and food residues. If you wish to measure the phosphorus content due to organic matter in the water sample using the vanadomolybdophosphoric acid method, you must first "digest" the sample to convert the organic phosphorus to orthophosphate.

What is the purpose of including a melting point in a procedure? A) As a method of purification - We can purify a substance. B) As a method of encouraging synthesis - Reagents are always more reactive in the liquid state. C) As a method of encouraging a substance to dissolve - Free molecules in the liquid state can make interactions and dissolve in the solvent easier. D) As a method of characterization We can identify an unknown substance. -- O A OD
You are employed as a coop student at the Drug and Alcohol Testing Association of Canada (DATAC) developing analytical tests for sports doping agents. You are asked to prepare a procedure for the extraction of methylphenidate, the active compound in Ritalin, from urine samples (consider them as simple aqueous layers, you do not need to consider other components!). The goal of the procedure is to extract the methylphenidate into an organic layer which will then be evaporated, and the residue will be tested for the drug.You find that methylphenidate is highly soluble in 2-methyltetrahydrofuran, a bio-renewable solvent. Draw the structure of 2-methyltetrahydrofuran and give two reasons why it is a good solvent choice for liquid-liquid extraction.
