Course overview
Joe Marc Valdez offers a compact pre-university organic chemistry course focused on structures, naming, functional groups and chemical behavior. The published material dates from 2017, making it a short foundation or revision option rather than evidence of a current examination specification. General chemistry knowledge is expected, and independent problem practice will add to the video time.
What you will learn
- Interpret displayed and skeletal formulas.
- Identify organic functional groups.
- Compare basic chemical reactions and behavior.
Who this suits
Pre-university learners and interested adults with a general chemistry background, as specified in the published requirements.
Before you enroll
Use the lessons for conceptual study and problem solving. Chemical demonstrations do not make an activity suitable for an unsupervised home experiment. Check the assumed mathematics and chemistry background, show units in calculations and compare your reasoning with worked solutions rather than memorizing an answer.
The official course page lists free enrollment. Udemy free courses do not include a completion certificate under its current policy. Check access terms before enrolling and treat downloadable notes as study aids rather than an accredited qualification.
Put it into practice
Draw three related organic compounds and name their functional groups. Explain one predicted difference in behavior and check your reasoning against an introductory chemistry reference.
