Representing Structures of Organic Molecules, Biology

Explore carbon and bonding with this activity. First, class members read a short excerpt about carbon and its characteristics. In response to the reading, they draw an electron dot diagram of carbon as well as diagrams of compounds...

There is 30 percent more carbon in the atmosphere today than there was 150 years ago. The first lesson in the four-part series teaches classes about the carbon cycle. Over two to three days, classes make a model of the cycle,...

Halogens comes from a Greek word which translates to make salt. Lesson 27 in the series of 36 teaches pupils about halogens. Pupils read, discuss, and answer questions in order to learn about haloalkanes and haloarenes. From defining...

Who is IUPAC and what they do? IUPAC is the organization that names and establishes rules for every organic compound. Find out more in a short video that focuses on prefixes, suffixes, functional groups, carbon chains, and cis or trans...

Sal continues to work through examples of more complicated carbon chains in this second video of five.

Sal continues to work through examples of more complicated carbon chains. He presents a complicated name and attempts to work through it logically, drawing the structure. His humor makes these strategies fun and easy to watch.

Help your class visualize cyclical ring-based carbon molecules. He translates a sawhorse projection into a "Double Newman" diagram, which helps clarify the respective energies and stabilities of molecules.

In the third of five videos, Sal continues to work through examples of more complicated carbon chains.

Hank talks about IUPAC, prefixes, suffixes, ranking, numbers for carbon chains, and cis or trans double bonds. [9:05]

This worksheet asks learners to work on alkane nomenclature. They name 2 straight-chain alkanes and answer 4 questions about branched-chain alkanes. In addition, class members name 5 branched-chain alkanes and draw the structures for 3...
