What is the hybridisation of each carbon in H2C = C = CH2.
H2C = C = CH2. The terminal carbons are sp2 hybridised as they form 3 (2 with H and 1 with C) sigma bonds and 1 pi bond(between carbons) while the centre carbon is sp hybridised (as it forms 2 sigma bonds, 1 with each carbon and 2 pi bonds, one with each carbon) .
