Verified step by step guidance
1
Identify the type of hydrocarbon: alkanes, alkenes, or alkynes. In this case, all are alkanes, which are saturated hydrocarbons with single bonds.
For part (a), 'propane' is an alkane with the prefix 'prop-' indicating three carbon atoms. The formula is C_3H_8.
For part (b), the formula CH_3CH_2CH_3 represents a linear chain of three carbon atoms, which corresponds to 'propane'.
For part (c), the formula CH_3CH_2CH_2CH_2CH_3 represents a linear chain of five carbon atoms, which corresponds to 'pentane'.
For part (d), 'octane' is an alkane with the prefix 'oct-' indicating eight carbon atoms. The formula is C_8H_18.
