Which of the following compounds is an isomer of butane? (2021)

Step 1: Understand what an isomer is. Isomers are compounds that have the same molecular formula but different structures.
Step 2: Identify the molecular formula of butane. Butane has the molecular formula C4H10.
Step 3: Look for compounds that also have the molecular formula C4H10.
Step 4: Check the structure of 2-methylpropane. It has the same number of carbon (C) and hydrogen (H) atoms as butane but is arranged differently.
Step 5: Confirm that 2-methylpropane is indeed an isomer of butane because it has the same molecular formula (C4H10) but a different structure.
