  1. 2. The "water-fearing" hydrocarbon tail of a soap molecule that interacts with oily dirt
  2. 3. The versatile element that forms the basis for all living structures and many everyday items
  3. 5. Carbon compounds where all carbon atoms are linked only by single bonds
  4. 7. A class of carbon compounds containing the –OH functional group, such as methanol or ethanol
  5. 10. The process of burning carbon or its compounds in oxygen to release carbon dioxide, heat, and light
  6. 11. The "water-loving" ionic end of a soap molecule that interacts with water
  7. 12. The functional group represented by the formula –CHO, found in compounds like propanal or hexanal
  8. 14. The chemical reaction used to prepare soap by treating an ester with an alkali like sodium hydroxide
  9. 16. A type of chemical bond formed by the sharing of an electron pair between two atoms
  10. 18. The property of carbon having four valence electrons, allowing it to bond with four other atoms
  11. 20. The industrial process of adding hydrogen to vegetable oils in the presence of a catalyst to make them saturated
  12. 22. A smooth and slippery allotrope of carbon that is a very good conductor of electricity
  13. 23. A sweet-smelling substance used in perfumes and flavorings, formed by the reaction of a carboxylic acid and an alcohol
  14. 25. Cleansing agents that remain effective in hard water because they do not form insoluble precipitates with calcium or magnesium ions
  15. 27. Compounds containing double or triple bonds between carbon atoms, which are generally more reactive than those with single bonds
Down
  1. 1. Organic compounds that consist entirely of the elements carbon and hydrogen
  2. 3. Carbon's unique ability to form long chains, branched chains, or rings by bonding with other carbon atoms
  3. 4. The group of organic acids, like ethanoic acid, characterized by the –COOH functional group
  4. 6. Molecules that have identical molecular formulae but different structural arrangements, such as the two forms of butane
  5. 8. A specific group of atoms, such as alcohol or aldehyde, that determines the characteristic chemical properties of an organic compound.
  6. 9. An allotrope of carbon where each atom is bonded to four others in a rigid three-dimensional structure, making it the hardest known substance
  7. 12. Unsaturated hydrocarbons that contain one or more carbon-to-carbon double bonds
  8. 13. A common household substance that consists of a 5–8% solution of acetic acid in water
  9. 15. Unsaturated hydrocarbons that contain one or more carbon-to-carbon triple bonds
  10. 17. A series of compounds where the same functional group substitutes for hydrogen in a carbon chain, with successive members differing by a –CH2– unit.
  11. 19. Saturated hydrocarbons where all carbon atoms are joined by single bonds and follow the general formula CnH2n+2.
  12. 21. A spherical structure formed by soap molecules in water where the oily dirt is trapped in the center
  13. 22. The name given to pure ethanoic acid because it often freezes into a solid during winter in cold climates
  14. 24. A functional group (>C=O) typically present in the middle of a carbon chain, such as in propanone
  15. 26. An insoluble, curdy substance formed when soap reacts with the calcium and magnesium salts present in hard water
