Define organic functional groups and use a general formula R-X. List some common functional groups which are present in aromatic hydrocarbons. Discuss alcohols and the alcohol functional group, OH. Review the nomenclature rules for naming alcohols, and use a few examples. Show the different ways of naming the same alcohol, using the official name, the common name, the usual name, and the old name. Define diols and triol alcohols, show structural formulas and discuss some usual and common names.
Define and discuss half life of radioactive isotopes. Compare the half life of radium, uranium and carbon to indicate the vast differences in theirs half life. Determine that after 20 half life's the amount of radioactivity becomes absent. Point out that radioactive decay is not affected by external conditions. Discuss how the half life is used to determine the age of an organic substance. Introduce the formula used to arrive at the age of an organic material. Work the formula amount remaining = original amount (No) x (1/2) ^t to arrive at the age of a substance. Discuss radioisotope use in diagnosis and treatment of some endocrine disorders.
Today we reviewed Joshua's work on the MCQs from Practice Test 1. I provided instruction and strategy for analyzing and answering the poetry questions. I noted the importance of first reading the introductory material. I then walked Joshua through an analysis of the first poem suggesting that while he reads to make sure he can recognize the significance of metaphors, and be able to identify shifts, and the narrative tone.I further explained the correct response to questions he missed and provided suggestions for choosing the best answer.
Review alpha decay. Introduce beta decay and neutron decomposition to form a proton and electron.
Discuss gamma rays, ions, and the changes in charge. Write the transmutation formula for uranium to thorium by Alpha decay. Show examples of beta decay of thorium by emission of an electron from the decomposition of a neutron. Write and discuss a complete radioactive decay series for thorium to lead
outline and discuss the following aromatic hydrocarbons. Aspartane, chlorobenzene, benzoic acid, aniline, phenol, and styrene. Discuss some common uses. Discuss ortho-meta-and para positions of additions to benzene. List and discuss 4-5 common properties of aromatic compounds. Outline that aromatics, like benzene do not undergo addition reactions, they undergo substitution reactions. Give examples of the 3 different types or substitutions
We began our review for the May 6 AP exam today. We first reviewed Joshua's essay on Hamlet and discussed the need to formulate a thesis i.e. a debatable interpretation that addresses the overall meaning of the play. I then on the board placed a review outlining the literary elements and techniques that are on the exam: first-character, narration, plot sequence and setting. Second, the techniques that implement these elements such as : figurative language, symbolism, imagery, juxtaposition , allusion, and symbols. I elaborated on the distinction between perspective and point of view and the AP exam's focus on complexity or tensions.
