Fill in the blank with the word(s) which best fit the description:
________________1. A subdivision of hydrocarbons where unsaturated hydrocarbons undergo substitution reactions easier than addition reactions.
________________2. A subdivision of hydrocarbons where unsaturated hydrocarbons undergo addition reactions easier than substitution reactions.
________________3. is an atom or group of atoms arranged in a particular way that is primarily responsible for the chemical and physical properties of the molecule in which it is found.
________________4. hydrocarbons are hydrocarbons which contain only carbon-carbon and carbon-hydrogen single bonds.
________________5. hydrocarbons are hydrocarbons which contain at least one carbon-carbon double or triple bond
________________6. Molecules having the same chemical formula but a different arrangement of atoms which make unique compounds that have different physical and chemical properties.
________________7. Because there is free rotation around a carbon-carbon single bond, there can exist unlimited number of forms. These different arrangements are called _____.
________________8. The hydrogen atoms of cyclohexane are described according to their position relative to the ring. Those that lie above or below the ring are said to be ____ atoms.
________________9. The hydrogen atoms of cyclohexane are described according to their position relative to the ring. Those that lie roughly in the plane of the ring are said to be ____ atoms.
________________10. The formation of cis-trans isomers, or ______isomers, is a consequence of the absence of free rotation in a cycloalkane or an alkene, which are stereoisomers that differ from one one another in the arrangement of substituents in space.
