How do you know if any active bromine is present in the reaction mixture or filtrate?
Homework Answers
Simple Bromine test: If any active Bromine present in reaction mixture or filtrate ML’s that means its color is brown of deep brown. Take few drops of reaction mixture or filtrate ML’s added into unsaturated compound solutions like phenol/ Aniline in dichloromethane. If the reaction mass or filtrate ML’s color disappears mean there was active bromine present. If not color disappears mean then there is no bromine.

Question 2: Consider the production of bromobenzene from benzene and bromine The reaction mixture contains 45.7 g of Benzene and 89.7 g of bromine. a) Which compound is the limiting reactant? b) What is the theoretical yield for bromobenzene? c) You conduct the experiment and you obtain 76.3 g of bromobenzene. What is the percent yield?

You enter the lab to analyze the chip filtrate for Cl?. First, you prepare a solution of silver nitrate, AgNO3, and titrate it against 0.500 g of KCl using the Mohr method. You find that it takes 62.7mL of AgNO3 titrant to fully reach the equivalence point of the reaction. You then use the same silver nitrate solution to analyze the chip filtrate in a Mohr reaction, finding that the solution yields a rusty brown precipitate when 47.9mL of titrant...

How do you determine if an addition of bromine to trans-stilbene is stereospecific based on the melting point of the product from the reaction? How would measuring the optical rotation of the product help identify it?

any excess bromine that persists after the reaction will
mostly be left in the choos: (filtered solid, filtrate, or reaction
vile) and quenched with the choose: (oxidizing agent, reducing
agent, strong acid, or strong base) choose: (acetic acid, methanol,
sodium bisulfate, sodium bisulfite).
Procedure: Bromination of E-Stilbene SAFETY INFORMATION Carry out this experiment in a fume hood and wear nitrile gloves. Pyridinium tribromide is an oxidizing agent, is corrosive, and can severe skin and eye burns. Glacial acetic severe skin...

As a food chemist for a major potato chip company you are responsible for determining the salt content of new potato chip products for the packaging label. The potato chips are seasoned with table salt, NaCI You weigh out a handful of the chips, boil them in water to extract the salt, and then filter the boiled chips to remove the soggy chip places You then analyze the chip filtrate for C concentration using the Mohr method.First you prepare a...
