Organic Chemistry Molecular Models Assignment
Use the molecular model kit to build and name all alkanes and their isomers up to six carbons. On your
own paper, write the structural formulas and names of each molecule.
Use the molecular model kit to build and name all alkenes and their isomers up to six carbons. Include
only the positional isomers (location of the double bond) and not any branched isomers. On your own
paper, write the structural formulas and names of each molecule.
Use the molecular model kit to build a model of benzene (C6H6).

1. Choose a molecule off of the drop-down menu
2. Click and drag to rotate (or choose the “spin” box)
3. To find bond angles, double click on a peripheral atom, single click on a central atom, and then
drag to another peripheral atom
4. Select the bond dipoles box to see polar covalent bonds within the molecule
5. Select the molecular dipole box to see the overall polarity (dipole moment) of the molecule
6. State the name of the molecule when the molecular formula is given. Write the molecular
formula of the molecule when the name is given
