Organic Chemistry I Laboratory

Course Description

CHM2210L – Organic Chemistry I Laboratory is a 1-credit-hour laboratory course that accompanies CHM2210 (Organic Chemistry I lecture). The course provides hands-on experience with the techniques, instrumentation, and reactions of organic chemistry. Students develop competency in fundamental organic laboratory techniques (separation, purification, characterization) and conduct guided experiments illustrating concepts from the corresponding lecture course.

Students learn to safely handle organic compounds, perform standard laboratory operations (extraction, distillation, recrystallization, chromatography), characterize organic compounds using physical properties and basic spectroscopy (IR, NMR, where instrumentation is available), and document experimental work in a professional laboratory notebook. The course emphasizes the development of scientific reasoning, careful observation, accurate documentation, and laboratory safety habits required for advanced study in chemistry, biochemistry, biology, and the health sciences.

CHM2210L is a Florida common course offered at approximately 31 Florida institutions. It is required for chemistry majors, biochemistry majors, biology majors planning graduate study, pre-medical students, pre-dental students, pre-pharmacy students, pre-veterinary students, and others entering health-professional programs. It is typically taken concurrently with CHM2210 (Organic Chemistry I lecture). It transfers as the equivalent course at all Florida public postsecondary institutions per SCNS articulation policy.

Special Information

General Education and Transfer

CHM2210L is a Florida common course number that transfers as the equivalent course at all Florida public postsecondary institutions per SCNS articulation policy. Together with CHM2210 (Organic Chemistry I lecture), it satisfies the natural-science with-laboratory general-education requirement at most Florida public colleges and universities and is required for chemistry, biochemistry, and life-science majors and pre-health pathways.

Concurrent Enrollment with CHM2210

CHM2210L is typically taken concurrently with or immediately after CHM2210 (Organic Chemistry I lecture). The lab course directly applies and reinforces concepts from the lecture; concurrent enrollment is the standard pathway. Some institutions require simultaneous enrollment.

Course Sequence

CHM2210L (with CHM2210) is the first half of the standard two-semester organic chemistry lab sequence:

• CHM2210C / CHM2210 + CHM2210L — Organic Chemistry I (lecture and lab; structure, bonding, stereochemistry, alkanes, alkenes, alkynes, alkyl halides, alcohols).
• CHM2211C / CHM2211 + CHM2211L — Organic Chemistry II (lecture and lab; aromatics, carbonyls, amines, biomolecules, NMR/MS in greater depth).

Some Florida institutions offer the integrated combined-course version (CHM2210C, CHM2211C) with the "C" indicating integrated lecture+lab. Other institutions split lecture (CHM2210, CHM2211) and lab (CHM2210L, CHM2211L) into separately enrolled courses. Both arrangements articulate similarly through SCNS.

Prerequisite Requirements

Students entering CHM2210L typically must have completed:

• CHM1045/CHM1045L (General Chemistry I + Lab) or CHM1045C with grade of C or better
• CHM1046/CHM1046L (General Chemistry II + Lab) or CHM1046C with grade of C or better — required at most institutions
• Co-enrollment in CHM2210 (Organic Chemistry I lecture)

Lab Safety and Personal Considerations

Organic chemistry laboratory work involves exposure to chemicals (solvents such as diethyl ether, acetone, methylene chloride, hexanes; reagents that can be hazardous if mishandled). Strict adherence to PPE, fume hood discipline, and safety protocols is essential. Students with allergies or sensitivities to organic solvents should consult their instructor before beginning lab work. Pregnant students should consult their healthcare provider regarding any specific exposure concerns.

Course Format

CHM2210L typically meets weekly for 3-4 hours of laboratory work. The course is offered primarily in face-to-face format due to the hands-on nature of the work; fully online versions of organic chemistry lab are uncommon (though virtual lab supplements are increasingly used).
