for 5 minutes. 0.3mL of ethyl iodide was then measured and pipetted at the top of the condenser. The vial/condenser apparatus was moved back onto the hotplate and heating blocks were placed around the vial. The solution was heated and stirred for 10 minutes at 60°-70°C. After 10 minutes, the temperature was increased to around 80°-90° and the solution started bubbling more vigorously. After 5-10 more minutes, a reflux (a foggy ring with condensation) formed towards the bottom third of the condenser. The hotplate was then turned off and the vial/condenser apparatus was moved away and allowed to cool for 5 minutes. On the side, the vacuum filtration apparatus was prepared and the filter paper was wet with DI water. 12-15 mL of ice water was also attained and placed in a 25 mL beaker. After being cooled for 5 minutes, the solution in the vial was poured into the ice/water beaker and stirred for 5 minutes. A mixture of thick, pale yellow slush was formed and allowed to melt. The mixture was vacuum filtered until the contents on top of the filter paper were dry and a white, powdery precipitate remained. A 4 mL [Na] + [OH] - [Na] + [I] -

Sanjeev Saravanakumar July 15, 2015 CHEM 230-2 TA: Kacper screw-cap vial (without the cap) was massed and recorded and then the product was transferred into the vial via spatula. The vial and solid (without the cap) was then massed again and recorded. The solid was then put through NMR spectroscopy, IR spectroscopy, and melting point instruments to attain their respective values.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
