Homework Answers
1a) Cholesterol is unsaturated because it contain a double bond in its structure.
b) Bromine water test can be used to test for undatunsatur as color changes from brown to colorless if compound is unsaturated.
2) Cl2 can't be used to detect unsaturation because it's color change is not sharp and also Br2 is more reactive than Cl2.

The following compound can be prepared by the addition of HBr to either of two alkenes, give their structures Start with the same two alkenes, would the products be different if DBr(D = deuterium) were used instead of HBr? Explain using a mechanism that outlines the tree steps of all organic chemical reactions. The reaction of alpha-pinene with H_2 in the presence o Pd/c produces A and not B. Why does product B not form?
