About the content
This is an introductory course for students with limited background in chemistry; basic concepts such as atomic and molecular structure, solutions, phases of matter, and quantitative problem solving will be emphasized with the goal of preparing students for further study in chemistry.
- Week 1 - Review Videos (I)
Welcome! Over the eight weeks of the Introduction to Chemistry: Structures and Solutions course, we will begin discussions about the electronic structure of the atom, structures of molecules, phases of matter, and solutions. This week, we included some basi...
- Week 1 - light
We will cover introduction to light, Bohr model of the hydrogen atom, atomic orbitals, electron configurations, valence versus core electrons. Don’t forget to use this week’s discussion forum for any questions and discussions.
- Week 2 - Quantum Number, Lewis Dot Structure
Welcome to week 2! This week we will introduce quantum numbers, more information about periodicity, chemical bonding concepts including Lewis dot structures, resonance, bond order. Continue using the discussion forum for any questions, concerns, discussions...
- Week 3 - Formal Charge, VSEPR Theory, Hybridization
Welcome to week 3! This week includes introduction to the octet rule and expanded octets, formal chargevalence shell electron pair repulsion (VSEPR) theory, sigma and pi bonds, hybridization of the main group elements, and introduction to molecular shapes.<...
- Week 4 - Phases of Matter, Gas Laws
Welcome to week 4! This week we will discuss phases of matter, the importance of thermal energy, ideal gas law calculations, kinetic molecular theory of gases. Hope you will enjoy!
We are at the midway point in the course! As a group you have been wa...
- Week 5 - Intermolecular Forces and Phase Changes
Welcome to week 5! This week we will examine the phases of matter more closely, looking at concepts such as intermolecular forces and thermal energy. We will also practice calculations of energetics such as those requiring enthalpies of phase transitions. ...
- Week 6 - Solutions
Welcome to week 6! We have reached the last week of video lectures and exercises for the course! Are you ready to make the final push through the rest of the material? After that, you should be ready to tackle the final exam which opens next week. I have en...
- Week 7 - Strengthen Your Understanding
Congratulations on making through to the final week of the course! For many of you it was not an easy journey for the past six weeks with dozens of videos, exercises, problem sets, and forum discussions. I am proud of all of you! The last components of the ...

Duke University is a private North American research university located in Durham, North Carolina. The university is named after the Duke dynasty.
Although the university was not officially founded until 1924 (its roots go back to 1838). Frequently referred to as the "Harvard of the South", Duke is the most selective university in the American South.
The university is a member of the Association of American Universities, an association which, since 1900, has brought together the elite research universities of North America.
