Organic Chemistry Lecture Announcements and Review Questions
Lecture announcements include details about an upcoming final exam and points distribution. Review questions focus on organic chemistry topics such as isomerism, functional groups, and carbon bonding in alkanes. The questions cover structures, properties, and reactions of organic compounds. Students are reminded of an assignment deadline and are provided with information about the exam format and location.

Presentation Transcript
Announcements I Mastering Ch. 20 assignment (Organic Chemistry) due 12/10 After that (and the hand grading problem), I will assign class points (probably some bonus to reflect some bad homework problems) Final Exam Thurs., 12/15 12:45 to 2:45 42 multiple choice questions (2 bonus, but no work out type) Using SC-982E Scantron form (Blue version used previously)
Announcements II Final Exam cont. About 4 questions each for Ch. 14, 15, 17, and 24 and about 8 questions each for Ch. 16, 18, and 20 Less calculation intensive than exams 1 and 2 Sect. 7 in Lab room (Sequoia 426)
