Alkane Isomers

Straight-chain, non-cyclic alkanes (also called acyclic alkanes) follow a simple general formula.  It's CₙH₂ₙ₊₂, where n is the number of carbon atoms. Let’s dive into the fascinating world of isomers molecules with the same formula but different structures!

Action

  1. Start with C₄H₁₀:

    • Enter C₄H₁₀ into the isomer app and click Submit.  How many isomers can you find? Can you name them? Take a guess before checking!

  2. Move on to C₅H₁₂:

    • Now, try C₅H₁₂. Enter the formula and click Submit.  How many isomers appear this time? Challenge yourself to name each one. Are there more than you expected?

  3. Level Up to C₆H₁₄:

    • Ready for a bigger challenge? Enter C₆H₁₄ and click Submit.  Count the isomers and try naming them. Do you notice a pattern emerging as the number of carbons increases?

  4. Final Challenge: C₇H₁₆:

    • For the ultimate test, enter C₇H₁₆ and click Submit. How many isomers can you find now? Can you name them all? Take your time—this one might surprise you!

As you explore, pay attention to how the number of isomers grows with each additional carbon atom. What do you notice about the complexity of the structures? Can you predict how many isomers C₈H₁₈ might have?
