1. Define the following terms:
a. Alkane: ​any of the series of saturated hydrocarbons including methane, ethane,
propane, and higher members
b. Alkene: ​any of the series of unsaturated hydrocarbons containing a double bond,
including ethylene and propylene.
c. Alkyne: ​any of the series of unsaturated hydrocarbons containing a triple bond,
including acetylene
2. Define and list an example of Structural isomer and stereoisomers:
a. Structural Isomers: ​molecules with the same molecular formula, but their atoms
have different arrangements or bonds (Ex: Butane and isobutane)
b. Stereoisomers: ​each of two or more compounds differing only in the spatial
arrangement of their atoms (Ex: Cis and trans)
