Ethanol boils at 78.4°C, water boils at 100°C, but it forms a positive azeotrope that boils at 78.2°C, which is lower than for either of its constituents. If you start from a mash that has 10% alcohol content, how many distillation steps do you require to get to 40% alcohol (typical for Vodka)? (use the figure below to sketch the steps). How many steps would be required to make Whiskey with 60% alcohol? Why can you not make a solution...

Assemble the glassware for fractional distillation according to the diagram and discussion above. Make certain that all joints are secure and that the apparatus is appropriately supported. Remember to allow for space below the distillation flask for the heating mantle and below the receiving flask for an ice bath. Pay extra attention to the positioning of the bulb of the thermometer as mentioned in the introduction. It is critical that the thermometer be positioned correctly for accurate temperature measurement. Using...

Need help with number 2 and 3 on the postlab section.
Elimination Reactions Background The purpose of this lab is to prepare an alkene by dehydration of an alcohol in the presence of an acid catalyst Elimination reactions often result in the formation of multiple products. In this lab, 2-methylcyclohexanol is dehydrated to form an alkene. The product will be analyzed by GC-MS to determine the ratio of alkene isomers formed. You will need to determine the mechanism of the...

PREPARATION OF PHARMACEUTICALS - Fischer Esterification
Reactions
Q: Calculate the expected mass of both methyl salicylate and
aspirin assuming 100% yield.
EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...

What is the SN2 reaction? How does Br attach to which carbon as
a nucleophile and why? Difference between Unimolecular or
Bimolecular? How NaBr and H2SO4 work in the
reaction? Why Water/Sulfuric Acid/Brine/Sodium
Hydroxide/Na2SO4 in Extraction? What does
each layer have inside in each step of the separation?
Please help. Due to corona, this is a theoretical lab and I am
very confused.
