n-Butane overview

The stored Lewis connectivity is CH₃—CH₂—CH₂—CH₃. The stored record represents the straight-chain n-butane isomer, with only single bonds.

How to draw C₄H₁₀

  1. Count 26 valence electrons. Include charge adjustments before drawing.
  2. Use the reviewed connectivity CH₃—CH₂—CH₂—CH₃. Do not infer a different isomer from the formula alone.
  3. Place the required single, double or multiple bonds. Keep a running electron total.
  4. Complete terminal valence shells and add lone pairs or formal charges. The stored record represents the straight-chain n-butane isomer, with only single bonds.
  5. Verify the total electron count and geometry. The reviewed geometry is Tetrahedral at each carbon.

Why this example matters

The stored record represents the straight-chain n-butane isomer, with only single bonds.

Scope and model limits

C₄H₁₀ also has the constitutional isomer isobutane. Entering the bare formula uses n-butane as the stored default.

Common mistakes

  • Assuming C₄H₁₀ has only one structure
  • Adding a C=C bond
  • Giving carbon lone pairs
