Nomenclature: Cyclic Hydrocarbons

Cyclic hydrocarbons form  ring structures  when the two ends of a hydrocarbon chain join together. In order to do this, a hydrogen atom from each end carbon must be removed. A common example is that of a six-carbon hexane forming the six-carbon cyclohexane, which has the formula C6H12. Notice that there are two less hydrogen than in hexane. The structural diagram of cyclic hydrocarbons is usually represented by a line diagram. The three images below are all cyclohexanes.

Nomenclature rules:

  • Add prefix “cyclo” to the name
  •  Any carbon can be carbon number 1 ;  branch is always given lowest possible position number. If there is only 1 branch, no position # is required as the branch is automatically on the first carbon atom.
  •  You can count in either direction around a ring, as long as the lowest position numbers are represented.
  •  A double bond is represented by an extra vertical line inside the ring structure.

End of year project: Mapping mass movements

Everyone will :

  • be working with a partner for this project.
  • research an event that has produced extraodinary mass movement in any country/city. Research paper should not exceed 3 pages and needs to include but is not limited to the following: Country, city, date, type of event that caused the mass movement, type of mass movement, explanation of mass movement, effects of mass movement on the land, structures, life , measures taken to aid and reduce possibilities of other occurrences and analysis of land elevationd and features before and after event and mass movement.
  • draw two topographic maps based on instructions provided in class that illustrate changes of land elevation and shape; one before mass movement and one after mass movement.  Maps must include picture of area.

*Research information and maps will be presented in class.
