If you measure the melting point of a sample, allowed the capillary to cool, and then measure the melting point of the sample a second time, will the second melting point reading be identical to the first? - Answer No - the crystal structure of the sample may change during the heating and cooling, and this will impact the melting point range. What effect do soluble impurities have on the melting point range of an organic compound? - Answer It decreases and broadens the range cy...

Tetrahydrogestrinone: Discovery, synthesis, and detection in urine - Answer - THG was identified in the residue of a spent syringe that had allegedly contained an anabolic steroid undetectable by sport doping control urine tests. - THG was synthesized by hydrogenation and gestrinone and characterized by mass spectrometry and NMR spectroscopy. - Developed and evaluated sensitive and specific methods for rapid screening of urine samples by liquid chromatography/tandem mass spectrometry (...

How do substituents on aromatic rings affect electrophilic aromatic substitution? - Answer They direct incoming groups Electrophilic aromatic substitution - Answer aromatic ring acts as nucleophile and attacks an electrophile, aromaticity of ring regenerated through loss of a proton EWG - Answer to position meta and deactivate the ring, ortho/para positions electron deficient (halogens-ortho and para even EWG) EDG - Answer to position ortho and para and activate ...

How a diesel engine works - Answer 1. Air is drawn into cylinder. 2. Motion of the piston compresses the air, heating it to a high temperature. 3. When the piston nears the top of the cylinder, fuel is injected under high pressure 4. Fuel quickly begins to vaporize though the hot air. 5. Spontaneous ignition takes place without the need for spark, causing rapid expansion, pushing the piston down and powering the vehicle 6. When the piston is close to its lowest position the exhaust va...

What is melting point? - Answer Temp range of the first crystal starts to melt and the last crystal completely melts. What is the melting point range of pure solids? - Answer Narrow What happens to the MP range with impurities? - Answer Lowers and broadens What is melting point dependent on? - Answer Stacking arrangement of crystalline lattice Why do impurities affect the mp of a compound? - Answer They cause defects in the crystalline lattice, making it...

Explain the purpose of the hot gravity filtration. Why is it good to use the stemless funnel for this technique? - Answer Hot gravity filtration is used in the process of recrystallization. Specifically, it is used to remove any insoluble impurities from the sample. It is good to use the stemless funnel for this technique because it prevents crystallization from occurring on the stem of the funnel (since stemless). To elaborate, if hot solution were to become stuck on the stem of the funne...

A teaching assistant found an old vial containing acetophenetidin synthesized by students from last semester. He measured its melting point to be 135.5-136.8C, which is very close to the theoretical value of 133-136C. Can he confirm that the compound is acetophenetidin just from this information? - Answer No, he would need to do a mixed melting point with some pure acetophenetidin If you measure the melting point of a sample, allowed the capillary to cool, and then measure the melting p...

diesel fuel - Answer heavier, oilier, higher boiling point, less refined, less expensive to produce, higher energy density, more efficient in burning fuels gasoline - Answer lighter, less oily, lower boiling point, more refined, more expensive to produce, lower energy density, less efficient in burning fuels biodiesel fuel - Answer made from vegetable oils and fats; non-toxic, biodegradable, lower pollution alternative to petroleum-based diesel fuel simple transesterif...

Which of the following best describes the purpose of IR Spectroscopy? a. To elucidate or confirm the identity of an unknown compound by identifying the functional group(s) present. b. To determine the identity of impurities in a mixture. c. To elucidate or confirm the identity of an unknown compound by measuring the carbon-hydrogen framework of the entire molecule. d. To determine the concentration in a mixture by separation based on polarity. - Answer a. To elucidate or confirm the i...

Is chlorophyll b more or less polar than chlorophyll a? - Answer Chlorophyll b should be more polar than chlorophyll a because the former has a CHO group where the latter only has a CH3 group. Which one is more polar? B-carotene vs. xanthophyll - Answer xanthophyll would be more polar than B-carotene because of the -OH group at the ends of the molecules. B-carotene contains no oxygen and is quite non polar. Ethyl acetate - Answer polar solvent (-CO interaction) Why do ...
