Isomerism exercises

Identify the type of structural isomerism between the pairs of compounds below.

1. Butane vs. 2-methylpropane (same formula C₄H₁₀)

Answer: chain isomerism (different carbon skeleton)

2. Propan-1-ol vs. propan-2-ol

Answer: position isomerism (-OH group at different positions)

3. Ethanol vs. methoxymethane (both C₂H₆O)

Answer: function isomerism (alcohol vs. ether)

4. But-1-ene vs. but-2-ene

Answer: position isomerism (double bond at different positions)
