1. - A compound with no double or triple bonds, containing only single bonds between carbon atoms.
4. - A term used to describe open-chain (non-cyclic) organic compounds.
6. - Any of the five elements in the 17th group of the periodic table (fluorine, chlorine, bromine, iodine, and astatine).
10. - A specific group of atoms or bonds within a molecule that is responsible for its characteristic chemical reactions.
12. - An organic compound consisting entirely of hydrogen and carbon atoms.
