Physical State of Unbranched Hydrocarbons Procedure: In the activity sheet, ENCIRCLE the compound if it is a gas, UNDERLINE the compound if it is a liquid, and BOX the compound if it is solid at room temperature. Unbranched alkanes and unbranched alkenes or alkynes with only one or triple bond containing 1 to 4 carbon atoms (C1-C4) are GASES at room temperature. Unbranched alkanes and unbranched alkenes or alkynes with only one or triple bond containing 5 to 17 carbon atoms (C5-C17) are LIQUIDS at room temperature. Unbranched alkanes and unbranched alkenes or alkynes with only one or triple bond containing 18 or more carbon atoms (≥ C18) are SOLIDS at room temperature. CH3CH2CH3 – It is a GAS because it is an unbranched alkane containing 3 carbon atoms. 1-Hexene – It is a LIQUID because it is an unbranched alkene containing 6 carbon atoms (if you will illustrate the structure) with only one double bond. CH≡C-(CH2)16 -CH3 – It is a SOLID because it is an unbranched alkyne containing 19 carbon atoms with only one triple bond. Unbranched cycloalkanes and unbranched cycloalkenes with only one double bond containing 3 to 4 carbon atoms (C3-C4) are GASES at room temperature. Unbranched cycloalkanes and unbranched cycloalkenes with only one double bond containing 5 to 8 carbon atoms (C5-C8) are LIQUIDS at room temperature. Unbranched cycloalkanes and unbranched cycloalkenes with only one double bond containing 9 or more carbon atoms (≥ C9) are SOLIDS at room temperature. Example: Cyclopropane - It is a GAS because it is an unbranched cycloalkane containing 3 carbon atoms. Cyclohexene - It is a LIQUID because it is an unbranched cycloalkene containing 6 carbon atoms with only one double bond. Cyclodecane - It is a SOLID because it is an unbranched cycloalkane containing 10 carbon atoms. Cyclononene It is a SOLID because it is an unbranched cycloalkene containing 9 carbon atoms with only one double bond. (Note: We will not include Cycloalkynes because they are unstable and rarely found in nature)
