Explanation:
The question asks for the compound whose chemical properties are similar to butane. To determine this, we need to understand the concept of homologous series and the chemical properties of butane.
Homologous Series:
A homologous series is a series of organic compounds that belong to the same family and possess the same functional group. They also show similar chemical properties. The members of a homologous series are called homologues and differ from each other by the number of CH2 units in the main carbon chain.
Chemical Properties of Butane:
Butane is an alkane with the molecular formula C4H10. It is a flammable gas that is commonly used as a fuel. Some of the chemical properties of butane include:
1. Combustibility: Butane readily undergoes combustion in the presence of oxygen, producing carbon dioxide and water.
2. Reactivity: Butane is relatively unreactive under normal conditions. It does not readily undergo chemical reactions with other substances.
3. Solubility: Butane is insoluble in water but dissolves in organic solvents such as ethanol or acetone.
Comparing Chemical Properties:
To determine which compound has similar chemical properties to butane, we need to consider the functional group and the number of CH2 units in the main carbon chain.
Option A: Butyne
Butyne is an alkyne with the molecular formula C4H6. It contains a triple bond between two carbon atoms. The presence of a triple bond significantly affects its chemical properties, making it more reactive than butane. Therefore, the chemical properties of butyne are not similar to butane.
Option B: Propene
Propene is an alkene with the molecular formula C3H6. It contains a double bond between two carbon atoms. Although propene and butane both belong to the same homologous series (alkenes), the difference in the number of CH2 units in the main carbon chain makes their chemical properties different. Therefore, the chemical properties of propene are not similar to butane.
Option C: Propyne
Propyne is an alkyne with the molecular formula C3H4. It contains a triple bond between two carbon atoms. Similar to butyne, the presence of a triple bond significantly affects its chemical properties, making it more reactive than butane. Therefore, the chemical properties of propyne are not similar to butane.
Option D: Pentane
Pentane is an alkane with the molecular formula C5H12. It contains five CH2 units in the main carbon chain, one more than butane. Since both butane and pentane belong to the same homologous series (alkanes) and have a similar chain length, their chemical properties are expected to be similar. Therefore, the chemical properties of pentane are similar to butane.
Therefore, the correct answer is option D, pentane.
