Q: What is true of the most stable resonance structure for CH2CH2?

Carbon is sp3 hybridized

Carbon bears a lone pair

There is one pi bond between the two carbon atoms

The bond order between the carbon-carbon bond is 2 Hydrogen bears a lone pair Carbon is sp2 hybridized

The molecular geometry around carbon is trigonal bipyramidal

The electronic geometry around carbon is trigonal planar

Answer 1

Magnetic quantum number - 3 means Electron belong to f orbitals
