GENERAL OBJECTIVES OF THIS COURSE:
The primary aim of this course is to present organic chemistry as a vigorous science based on a well-developed theory and to show its application in society. To attain this end, the first semester of this two-semester course will:
- Include essential principles (such as nomenclature, molecular structure, functional groups, stereochemistry) and simple reactions (such as those of the aliphatic hydrocarbons, halides, alcohols, phenols and ethers) so as to give the student thorough training in the fundamentals of organic chemistry.
- Interpret organic reactions in terms of modern theories of electronic structure and geometry, thereby enabling the student to recognize the fundamental mechanisms which relate the many types of organic reactions.
- Involve the student in laboratory sessions which are designed to complement the lecture material so that a more thorough understanding of organic chemistry is achieved at the same time that practical laboratory techniques are developed. Some of these techniques include: gas chromatography, refractometry, polarimetry and infrared spectroscopy along with, fractional and vacuum distillations, and extractions.
SPECIFIC OBJECTIVES OF THIS COURSE:
