Ethene's structure hinges on understanding how $sp^2$ hybridization creates both single and double bonds. The key is to count systematically: each C–C and C–H connection contributes one σ bond, while the double bond between carbons contains one additional π bond on top of its σ bond. Sketch the Lewis structure to visualize all four hydrogens and the C=C double bond, then tally each bond type separately.
