Question

question 4 (1 point)
which compound is a structural isomer of the compound shown below?

propane
butane
methane
pentane
hexane

Explanation:

Step1: Determine the molecular formula of the given compound

The given compound is neopentane. Counting the number of carbon and hydrogen atoms, its molecular formula is \(C_5H_{12}\).

Step2: Check the molecular formula of each option

• Propane: \(C_3H_8\)
• Butane: \(C_4H_{10}\)
• Methane: \(CH_4\)
• Pentane: \(C_5H_{12}\)
• Hexane: \(C_6H_{14}\)

Structural isomers have the same molecular formula. Since the given compound (\(C_5H_{12}\)) and pentane (\(C_5H_{12}\)) have the same molecular formula, pentane is the structural isomer.

Answer:

pentane
