Across
  1. 2. cyclic hydrocarbons that contain single bonds only and can have rings with three, four, five, six, or more carbon atoms
  2. 4. a hydrocarbon that contains only single bonds
  3. 5. a category of stereoisomers that results from different arrangements of groups around a double bond
  4. 9. a hydrocarbon that contains at least one double or triple bond between carbon atoms
  5. 12. the process by which petroleum can be separated into simpler components, called fraction, as they condense at different temperatures
  6. 14. a carbon atom that has four different atoms or groups of atoms attached to it; occurs in chiral compounds
  7. 16. organic compounds that contain one or more benzene rings as apart of their molecular structure
  8. 18. result from different arrangements of four different groups around the same carbon atom and have the same physical and chemical properties except in chemical reactions where chirality is important
  9. 20. the sidebranches that extend from the parent chain
  10. 21. onaromatic hydrocarbons, such as alkanes, alkenes, and alkynes
  11. 22. the process by which heavier fractions of petroleum are converted to gasoline by breaking the large molecules into smaller molecules
  12. 23. class of isomers whose atoms are bonded in different orders with the result that they have different chemical and physical properties despite having the same formula
Down
  1. 1. an unsaturated hydrocarbon with one or more double covalent bonds between carbon atoms in a chain
  2. 3. simplest organic compound composed only of the elements carbon and hydrogen
  3. 6. the longest continuous chain of carbon atoms in a branched-chain alkane,alkene, or alkyne
  4. 7. hydrocarbon that contains only single bonds between atoms
  5. 8. an organic compound that contains a hydrocarbon ring
  6. 10. an effect that occurs when polarized light passes through a solution containing an optical isomer and the plane of polarization is rotated to the right by a d-isomer or to the left by an l-isomer
  7. 11. a property of a compound to exist to the left (-l) and right (d-) forms; occurs whenever a compound contains an asymmetric carbon
  8. 13. two or more compounds that have the same molecular formula but have different molecular structures
  9. 14. a unsaturated hydrocarbon with one or more triple bonds between carbon atoms in a chain
  10. 15. all compounds that contain carbon with some primary exceptions
  11. 17. describes a series of compounds that differ from one another by repeating unit
  12. 19. a class of isomers whose atoms are bonded in the same order but are arranged differently in space
