Methyl amine. B) Each carbon atom is sp 2 hybridized. C2H4 is sp 2 hybridized. However, to form benzene, the carbon atoms will need one hydrogen and two carbons to form bonds. Explain, how is the electronegativity of carbon atoms related to their state of hybridisation in an organic compound? In benzene, each Carbon atom has 3 σ bonds and 1 π bond. When one carbon atom hooks up with five others, all of the C are in the same plane, as are the 6 H atoms attached to them, so benzene is a flat or planar molecule. Benzene is an organic chemical compound with the molecular formula C 6 H 6.The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Carbon atoms in the benzene ring have a trigonal planar geometry around them since the carry bonds with three other groups and therefore, the hybridization is sp2 . In the case of ethene, there is a difference from, say, methane or ethane, because each carbon is only joining to three other atoms rather than four. plz give reasons.. im confused :-/ Share with your friends. What is the type of hybridisation of C atoms in benzene? 5. They all have sp2 hybridization. Hybridization of C in benzene=sp2. So, this makes a distortion in the original benzene ring (rest 4C’s are “sp2” hybridized; original π bond is unchanged but the orbitals that form the new π bond are not parallel to each other (due to poor overlap).
