List the series of alkene molecules by name. Have Ben draw the molecular formula for each molecule, using at least two methods.
Name each molecule based on the IUPAC name.
Introduce the methods used for proper nomenclature of alkanes and branched alkanes. Outline using a series of molecules how to properly name some simple to more complex alkanes and branched alkanes. Indicate how to write a structural formula from complex to simple. Sketch a complex alkane formula on the board, and have
Ben work out the proper international formula. The problem contains an assortment of methyl groups, ethyl groups, varying length carbon chains and numbering.

Lesson Comments
Ben was able to correctly work the name of the complex organic problem
Outline the first 5 alkanes and then discuss the alkyl groups associated with them. Define them as alkanes minus a hydrogen atom. Draw the structural formulas for methyl and ethyl groups. Depict how they become attached to an alkane to form a side group. Work the nomemclature of the groups. Show the numbering system.
Today I subbed for Ben (my student Carson was absent). Mr. Dan had us watch a YouTube video on Organic Chemistry. Afterwards we discussed what we watched. He explained to me that in order for something to be organic it must contain carbon. So Organic chemistry includes objects which have carbon in them.
Continue with the study of alkane molecules. Construct butane, sketch the structural formula, note the molecular formula, and then construct iso butane. Elicit the differences in the structural formula, but not in the molecular formula. Define these as isotopes. From methane, ethane, propane and butane, define the alkyl groups methyl, ethyl,propyl, and butyl.
Show how carbon must always have 4 bonds in a molecule. Discuss methane and its molecular formula, writing the formula on the board. Write the molecular formulas for methane, ethane, propane, butane, pentane, and hexane. Discuss the ANE ending and that it indicates an alkane compound. Define an alkane compound. Use molecular models and have Ben construct an ethane molecule. Determine from all the formulas that each succeding alkane differs by only one CH2 molecule.

Lesson Comments
Ben seems very interested in this area or chemistry
Introduction to organic chemistry. Compare the old definition and the new definition. Discuss how Wohler's synthesis of urea started the science of organic chemistry. Discuss how most new synthetic products are generated from a knowledge of organic chemistry. Show the structural formula and the molecular formula for urea.
Today's session focused on covalent compound naming and formula writing. Elise at the front desk scanned chapter 4 of Ben's chemistry textbook as he was working from home. Ben reviewed the chapter and gave the formula for the molecules listed in exercise 4.2, p. 57. This marks the completion of chapter 4. Ben should be able to recognize the naming system used for covalent molecules, identify a prefix with a number, give the names of covalent molecules from their formula, and give the formula of covalent molecules from their name.
