Concept introduction:
A synthetic trap is a synthesis which prevents the reaction from occurring in the forward direction as planned. This occurs mainly because the reactant molecule contains multiple functional groups which interfere in the desired mechanism. However, even when there is only one functional group, a synthetic trap can still arise if a reaction takes place at two or more sites within that functional group. In such cases, regiochemistry is an issue. Regiochemistry is the specific region in the given molecule at which the reaction takes place selectively. We can choose a synthesis according to the regioselectivities of the functional group transformation reactions.
In epoxide ring opening reactions, the regiochemistry can be controlled using acidic or basic/neutral medium. The nucleophile tends to attack the most substituted carbon atom under acidic conditions whereas a nucleophile tends to attack the least substituted carbon atom under neutral or basic conditions.

For each isomer, give all the free radical monochlorination and monobromination products that are structurally isomeric.arrow_forwardQ9. The insecticide DDT (in the box below) is useful in controlling mosquito populations and has low toxicity to humans, but is dangerous to birds and fish. Hoping to alleviate the dangers, little Johnny Whizbang, an aspiring chemist, proposes a new version of DDT ("Bromo-DDT") and shows his synthesis to his boss. Will Johnny Whizbang's synthesis work? Or will he be fired? Assume there is an excess of bromine and polybrominated products can be separated. Explain why.

If your graphs revealed relationship between specific heat and atomic revealed a mathematical mass, write down an equation for the relationship. Comment on the usefulness of the determination of specific heat as a method for identifying an element. Would specific heat alone give you much confidence with regard to the identity of the element? If you think measurement of another property would be needed to support an identification, what property would you measure and why? The elements listed in the table are all selected metals.
