Suggest a chemical test from one of these five tests: Permanganate test, Bromine test, Ammonciacal Silver Nitrate test, Sulfuric acid test, or the Sodium metal test that one could use to distinguish between 3-bromo-3-methylpentane and bromobenzene. Mention the expected observations.

Expert Solution

Bromine test:

In organic chemistry, the bromine test is a qualitative test for the presence of unsaturation (carbon to carbon double or triple bonds).

An unknown sample is treated with a small amount of elemental bromine in an organic solvent, such as dichloromethane or carbon tetrachloride. Presence of unsaturation in the sample is shown by disappearance of the deep brown coloration of bromine when it has reacted with the unknown sample.

The more unsaturated an unknown is, the more bromine it reacts with, and the less coloured the solution will appear.

3-Bromo -3-methyl pentane does not give positive test with the Bromine due to the absence of the unsaturation. Then we can distinguish from the Bromo benzene.

Two standardized tests, test A and test B, use very different scales. Assume that in one year the distribution of scores on test A can be modeled by N(1000, 75) and scores on test B can be modeled by N(27, 4). If an applicant to a university has taken test A and scored 1220 and another student has taken test B and scored 39, compare these students' scores using z-values. Which one has a higher relative score? Explain.

To reduce laboratory costs, water samples from five public swimming pools are combined for one test for the presence of bacteria. Further testing is done only if the combined sample tests positive. Based on past results, there is a 0.007 probability of finding bacteria in a public swimming area. Find the probability that a combined sample from five public swimming areas will reveal the presence of bacteria. Is the probability low enough so that further testing of the individual samples...
