【正文】 1 CHM 211 (Organic Chemistry) Summer 2022 ? Dr. Ned H. Martin ? Office: Dobo 242E ? Telephone: ? 9623453 (campus) ? Email: 2 Texts ? Organic Chemistry, 7th edition, McMurry ? Optional ? Study Guide and Solutions Manual for McMurry39。s Organic Chemistry, 7th edition ? Molecular model kit ? Course Website (Syllabus, Grading Policy): 3 Grading Policy ? Four 40minute tests, each worth 60 points. ? The final exam will consist of six sections. The first four are like the four tests。 the higher grade counts. Section 5 is new material (since the last test). Section 6 is prehensive. You may take (or not) as many of the first four sections as you want. Everyone must take sections 5 and 6. ? There will be no make up exams. ? Each of the tests may include at least one problem from the homework assignments. Tests 2 4 may contain one review question from the previous test. ? 93%=A, 90%=A, 87%=B+, 84%=B, 80%=B, etc. 4 Attendance amp。 Homework ? Attendance is expected, but not officially monitored for grading purposes. ? Missing 1 day in the summer is like missing 1 week during a regular semester! ? Homework problems are assigned, but not collected. ? Actively working the homework problems allows you to test whether you understand the material and serves as a review guide for the exams. 5 Keys to Success in CHM 211 ? Memorization alone is not sufficient. ? Reasoning alone is not sufficient. ? Study three times: ? Before the lecture ? After the lecture ? Before the test ? Actively do problems (Keep a notebook). ? Cooperate – form study groups. 6 What is Organic Chemistry? ? The study of carboncontaining pounds ? Important because: ? Carbon forms 4 bonds, and can bond to itself in long chains ? Carbon has three different geometries giving rise to a variety of structures ? Carbon bonds strongly to other mon elements: O, N, Cl, etc. ? Organic pounds have many applications and uses: dyes, medicines, fabric, plastics, food (protein, carbohydrates, fats, oils), fuel, pesticides, paint, preservatives, hormones, etc. ? This PowerPoint covers: Chapter 1. Structure and Bonding 7 C (Carbon) ? Carbon’s atomic number = 6, therefore it has 6 protons in its nucleus. ? A neutral atom of 12C has 6 protons, 6 neutrons and 6 electrons。 its amu = 12 ( = 6p + 6n) ? A neutral atom of 13C has 6 protons, 7 neutrons and 6 electrons。 its amu = 13 ( = 6p + 7n) ? A neutral atom of 14C has ? protons, ? neutrons and ? electrons。 its amu = ? ( = ?p + ?n) ? Carbon’s atomic weight = 。 this is a weighted average of the three isotopes: 12C, 13C, and 14C. 8 Parts of an Atom ? Protons (+ charge) and neutrons (0 charge) are in the center or nucleus of the atom
