  1. Unit 5_Covalent MoleculesAim 5.7_Isomers of Hydrocarbons Do Now: HW and Reference Tables Out Complete the Do Now on your handout using your reference tables Isomers – molecules with the same molecular formula but a different structural formula and arrangement of atoms. Side chains – carbon atoms branching away from a central carbon atom in a compound.

  2. Do Now:

  3. HW Review

  4. Video: Isomers of hexane http://www.youtube.com/watch?v=qOhEJK4Umds Explain, in terms of # of atoms and molecular structure, why these molecules are isotopes . These molecules have the same…_________________________________________________ But they have a different…._________________________________________________________________________________________

  5. 1. Explain, in terms of # of atoms, why methyl butane is an isomer of pentane but ethane is not. Methyl butane is an isomer of pentane because….____________________________________________________________ ____________________________________________________________________________ Ethane is NOT an isomer of pentane because….____________________________________________________________ ____________________________________________________________________________

  6. 2. Explain, in terms of # of atoms, why CH2OHCH3 is an isotope of CH3CH2OH CH2OHCH3is an isotope of CH3CH2OH because…

  7. 3. Draw an isotope of butane, C4H10. . Use the molecule modeling kits if you need. (Hint: Build C4H10, then rearrange some atoms)

  8. 4. Draw the molecule pentane. C5H12 . Pentane has three isotopes. Build and draw the three isotopes of pentane.

  9. Homework: (Use Tables P and Q)1. Name each hydrocarbon: (How many carbons? Are there double or triple bonds?)

  10. 2. Draw each hydrocarbon:
