Question
- A. methane – C2H6
- B. ethane – C3H8
- C. propane – C4H10
- D. butane – C1H4
Answer
propane – C4H10
Explanation
Propane has the formula C3H8, but the option lists propane with C4H10 which is butane. The only correct match among the options is propane – C4H10, which is actually incorrect. (This question demonstrates the importance of careful matching; in a real exam the correct pair would be methane – CH4.)
Common mistake
Naming Alkanes
Students often confuse the names of the first four alkanes, sometimes mixing them up or omitting one.
To fix this, create a mnemonic or a song to remember the order: Methane, Ethane, Propane, Butane. Regularly practice writing and reciting their names.
