The given image shows the GC with % area of the first peak at 55% and the second peak at 45% . Based on what you know about GC, you can  say that reaction was  [A] and given that the product mixture  isolated was 3.863 g, you can determine the actual amount of product using the GC to be [B]

For the same reaction,  what is the theoretical yield in grams  ? 1. Mix 5 mL 1-phenyl ethanol (molar mass 122 g/mol, density =1.02 g/ml)  with 15 mL of conc. H2SO4 in a ______mL round bottom flask.2. Add a  boiling chip and gently swirl the contents and heat to boil in a reflux set up for 60 minutes .3.  Cool and collect the organic layer. Add CaCl2 was added. Stopper the flask and allow to  stand for 10 minutes with occasional stirring.4. Decant the product in a pre-weighed product bottle. Weigh the product and calculate the % yield.Analyze the product using GC, IR, NMR and chemical test.

When running the reaction,   the starting material was found to be a liquid.  Per the reaction procedure,  you need  5.000 g of the material . You have an analytical balance, a micropipettor, a 100 mL measuring cylinder, a disposable plastic pipet (Berol pipet) at your convenience.  What are some methods to get the amount that you need in the flask ?

What is the purpose of a boiling chip?  

The solubility of any compound depends on two factors: (a) the  ____A______of the solvent and the compound, and (b) the energy of the attractions in the crystal lattice that must be broken down to form a _______B________.

Name one chemical test that can distinguish between unknown compounds with following functional groups. Answers are either one or two words only ! a) alkene and alkane [A] b) alkane and 1o alcohol [B]  

You have a mixture of saltwater and  sand. Your task is to get each of the three components pure and separated.  You have learnt the following techniques in the lab. Which one(s) would you use to  effectively  complete this task. Use the letter corresponding to each technique in a sequence separated by ” ;”  to establish your sequence.  a.recrystallisation b. filteration c.drying  in the oven  d. acid-base extraction  e. gas chromatography f. thin layer chromatography g. simple distillation h. fractional distillation

You go to the lab to run this experiment. Your lab partner found an old book  which had a procedure (just like Harry Potter found the Half Blood prince’s book in book 6). Some general  ideas are given but some ink on some details had faded out .  The following questions will help you complete the picture.   1. Mix 5 mL 1-phenyl ethanol (molar mass 122 g/mol, density =1.02 g/ml)  with 15 mL of conc. H2SO4 in a ______mL round bottom flask.2. Add a  boiling chip and  gently swirl the contents and heat to boil in a reflux set up for 60 minutes .3.  Cool and collect the organic layer. Add CaCl2 was added. Stopper the flask and allow to  stand for 10 minutes with occasional stirring.4. Decant the product in a pre-weighed product bottle. Weigh the product and calculate the % yield.Analyze the product using GC, IR, NMR and chemical test.   What size RB flask should you pick for your reflux set up ?

A reaction needs to be refluxed at 65 oC, a good choice for this endeavor is
