1,6-Methano[10]annulene , 1,6-methanonaphthalene or homonaphthalene is a hydrocarbon with chemical formula C11H12.
It is achieved by replacing two hydrogen atoms of [10]annulene by a methylene bridge (-CH
2-). This compound is aromatic as judged from lack in bond length alternation by x-ray crystallography and a telltale diamagnetic ring current from NMR spectroscopy.
It's resonance energy is smaller than naphthalene.[1]
