Organic Chemistry IV(2.0 credits)
|Course Type||:||Specialized Courses|
|Starts 1||:||3 Spring Semester|
|Lecturer||:||Jiyoung SHIN Designated Professor|
|The primary purpose of this course is to acquire a logical framework for understanding advanced organic chemistry. The course begins with condensation reactions of carbonyl and amine compounds and moves on to various reactions comprising migration steps. It also continues heterocyclic chemistry and organometallic chemistry, which are rapidly-expanding fields. Organometallic compounds that incorporate the carbon-metal bonds as powerful nucleophiles have been widely used for effective synthetic transformation. Replacement of the first metal by a new one can activate or control the chemical reactions' outcomes. Based on the knowledge, the participants are expected to conduct how to perceive appropriate answers to challenging problems in organic chemistry.|

|Examination (total 70%: midterm (30%) and final (40%)), Assessment of Homework (30%): Credits will be awarded to those students who score 60 or more. Grades are as follows: S(x≧90), A(90>x≧80), B(80>x≧70), C(70>x≧60), and F(60>x). The assessment methods will be reconsidered following a pandemic condition.|
|Submission of "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).
This assessment can be reconsidered within pandemic conditions where the attendance can be replaced with the submission of assignments.
|Students can communicate with the course instructor face-to-face either in the class or through the appointment. Communication through emails (instructor's e-mail: firstname.lastname@example.org and email@example.com) is also available.
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.
