b) Explain, using hybridization theory and diagram, the structure of allene,
Sure! Let’s carefully analyze allene ($CH_2=C=CH_2$) using hybridization theory and understand its structure with diagrams. --- ### Step 1: Identify the hybridization of each carbon atom Allene has the structure: $$ CH_2 = C = CH_2 $$ We have three carbon atoms: 1. Central carbon (C2): * It forms two double bonds (one with each terminal carbon). * Double bond = 1 sigma (σ) + 1 pi (π). * Sigma bonds around C2: 2 (one to each C). * No lone pairs. * Geometry: Linear along the ____ _________ __________ _____ _______ _______ ______ ___.
