Organic Chemistry V(2.0 credits)
|Course Type||:||Specialized Courses|
|Starts 1||:||3 Autumn Semester|
|Lecturer||:||Jiyoung SHIN Professor|
|This course was established to learn spectroscopic analysis of organic molecules and how to interpret spectral data. The course begins with theoretical/fundamental knowledge on the chromatographic and spectroscopic techniques (GC, HPLC, NMR, UV, IR, Raman, Mass, and so on) and continues to assignments of organic molecular structures with Spectra-type problems. Furthermore, it covers problem-solving regarding organic reactions to reinforce students’ understanding of molecular structures/reactivities. The participants are expected to solve the progressive problems sequentially.|

|Examination [total 70%: midterm (30%) and final (40%)] and Assessment of Homework and attendances (30%): S(x90), A(90>x80), B(80>x70), C(70>x60), and F(60>x) for the students who entered earlier than 2020; A+(95), A(95>xx80), B(80>x70), C(70>x65), C-(65>x60), and F(60x) for the students who entered in 2020 or later than 2020.|
|Submission of the "Course Withdrawal Request Form is necessary to withdraw the course. The student needs to contact the course instructor when the student wants to withdraw from the course. In the cases of any unavoidable reasons such as sickness, accident, or no attendance school, the student may get a grade of 'Absent' through the judgment of the course instructor and the student when the student submits a 'Course Withdrawal Request Form' to receive the 'Absent' grade. No submission of sickness/absence reports and lack of attendance score will result in an 'F' grade: It is for the protection of other attendances in the corresponding course from the frequent absences of the specific/uncertain student(s).
The course schedule can be reconsidered within pandemic conditions.
|Students can communicate with the course instructor face-to-face, either in the class or through the appointment. Communication through emails is also available (instructor's e-mail: jyshin321(at)gamil.com).
Lecture material for each class will be provided through NUCT. Students are recommended to review the lectures by solving the related homework questions. Each assignment is due by the start of the next class if it is not specially announced. Sudden questions can be given to students during lectures to provide substantial feedback.
