CHM4251 ORGANIC CHEMISTRY II COURSE PROCEDURE


CHM4251 ORGANIC CHEMISTRY II

5 Credit Hours

Student Level:

This course is open to students on the college level in the sophomore year.

Catalog Description:

CHM4251 - Organic Chemistry II (N) (5 hrs.) 

A continuation of CHM5250 Organic Chemistry I. This course is an introduction to NMR, IR, and mass spectroscopy, synthetic organic chemistry, and compounds of biological interest. This course is for science and pre-professional students and includes laboratory experimentation.

Course Classification: 

3 cr. Lecture/ 2 cr. Lab

Prerequisite: 

CHM4250 Organic Chemistry I and basic computer skills.

Controlling Purpose: 

This is the second semester of a two-semester course in organic chemistry.  This material will allow the student to become functional in the mechanistic rational for the behavior of organic reactants and important synthetic reaction mechanisms.  The student will also be able to read and interpret IR, MNR, and mass spectrometer data.

Learner Outcomes:

Upon completion of the course, the student will have the conceptual tools to understand and apply the relationship between the structures of organic compounds and their properties.

Based on classroom occupancy

Course Timeframe:  

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
