Spring '09 exam 1 key: Summer '13 exam 1 (65 min) Summer '13 exam 1 key Key as Pencast: Spring '09 exam 2 (50 min.) abstraction, heats of reaction, Exam 1: Hybridization, Organic synthesis. This is one of over 2,200 courses on OCW. AQA Chemistry. Science Practice Questions. 2) Studying practice exams in groups is generally more enjoyable for people, which leads to more time spent on the subject. Pick one of … Let me preface this by saying YES, this is a tough question. Typically, organic chemistry is taught over the course of two semesters or quarters. Your answer for Question #9 is wrong. So instead, I crossed out my four and a half steps and wrote a detailed step by step procedure for carrying out fractional distillation. Instead, write the four steps and add in as much relevant information as possible. Of course, when you are choosing study partners on the Serengeti, you need to be very careful to stay away from the jackals. It’s not so scary at first, think about the simple acid/base deprotonation, an alkene reaction here, another there. So, if you can only remember four of five steps, DO NOT leave it blank to receive zero points! You So while you don’t have to show a reagent simply draw ‘KET’ over the reaction arrow for Keto Enol Tautomerization. These are typically the first reactions discussed in any organic chemistry course; however, the principles behind these reactions (nucleophile, good leaving group, steric hindrance) can be applied to the whole course, explaining many reactions later on: for instance, the Sn1 and E1 reactions proceed through a carbocation intermediate. Reactions. So here I am, out of sheer curiosity, taking the chemistry test here on your site, and I found two incorrect answers on your answer key. Retrosynthetic Analysis or simply retrosynthesis, http://leah4sci.com/wp-content/uploads/2016/11/Moving-Reactivity-can-help-react-a-different-portion-of-the-molecule-using-intermediates-and-then-Mark-or-Anti-Markovnikov-addition.jpg, - Aromaticity & Electrophilic Aromatic Substitution (EAS), Alkene Reactions Overview Cheat Sheet – Organic Chemistry, Introduction To MCAT Math Without A Calculator, Keto Enol Tautomerization Reaction and Mechanism. Assess learning with questions about the reactions of alkanes and alcohols. Email us if you have any suggestions for the website or products that might be helpful. in this example we’re starting with a 3-carbon chain yet ending with a 4-carbon chain. In future weeks, there will only be 3. No pi bond? Or a radical halogenation if starting with an alkane? These are the students that are more parasite than human C) Go from there. What if you’re asked to start with an alkyne? Covers If you only remember the steps, but don’t remember which reagents will get you there, start by drawing out the molecules: For example, if you forget that an alkyne will react with HgSO4 in H2SO4 to yield a ketone. Organic synthesis “What do I have in the product?” You’re asked to ‘memorize’ each one, to know what every reactant and reagent will do. Again, I’m not asking you to invent on your exam.
