-------------------------------------------------

(10C-15C variations acceptable)

Reasons %yield: A reason which our percent yield is lower then what is satisfactory can be because of various factors. First, the number of product were working with is only. 1g a very small quantity. Little by little could possibly be loss through transfers, scrapings, Hirsch channel suction, and dried-product still left on the a glass in the test tubes. If perhaps,. 01g can be lost through these operations, this means essentially 10% yield reduction each time. For instance , during transactions from considering paper to beakers, a lot of product could be left over inside the paper. Also, another component could be due to heating. If we accidently hard boiled are contents to high, we could have got melted the item and lost it permanently. -------------------------------------------------

Reasons Melting Point: Professor provides told all of us that our burning point is acceptable. The main reason is because during the Evap, the reaction occurred and so fast very much of the solvent is included in the crystals. Therefore the actual shedding point is nearly impossible to succeed in, and 10C-15C variation is acceptable.

Questions

1). The infrared reading assessment between camphor and borneol+isoborenol is that camphor does not have a OH-stretch at 3400, but it has a C=O stretch about 1700-1750 that borenol and isoborneol doesn't always have. The IRGI readings of isoborneol and borneol look very similar difficulties difference is that isoborneol has a higher power reading from your 1500-1000 wavenumbers. 2). The peaks vary due to the situation of the WOW. In borenol, the OH is in the endo position, making it further far from both of the methyl groupings, this is why they have...
