How do you find #sp^2# carbons? Organic Chemistry Hybridization and Atomic and Molecular Orbitals Molecular Orbitals and Hybridizations 1 Answer Harsh · Grace May 13, 2016 A carbon having three #sigma# and one #pi# bond is #sp^2# carbon. While a carbon having 2 #sigma# and 2 #pi# is #sp# carbon. eg. # O=C=O# In the molecule of carbon dioxide (#CO_2#) , carbon is having 2 #sigma# and 2 #pi# so the carbon is #sp# hybridised. eg. in ethene ( #C_2H_4# ) each carbon is having 3 #sigma# and one #pi# , hence #sp^2# hybridised.
