WebThe tetrahedral point groups are characterized by the presence of four C 3 principal axes (and three C 2 axes). The T d group is the point group of a regular tetrahedron. If, in addition, a center of inversion is present, the point group is T h (molecules of this group do not look like tetrahedrons, but retain the rotational symmetry of a tetrahedron).

The symmetry is observed across three planes, one bisecting C 2 − C 3 {\rm{C2 - C3}} C 2 − C 3 bonds and C 6 − C 7 {\rm{C6 - C7}} C 6 − C 7 bonds in naphthalene, another plane at which the carbon atoms are sharing electrons, and the plane where carbon atoms occupy.
Web8. You are assuming that all resonance structures contribute equally. The resonance structures on the right and left are equivalent but have one aromatic ring and one non-aromatic ring. This is in contrast to the center resonance structure, which has two aromatic rings and is more stable, thus giving the bonds between carbons 1-2; 3-4; 5-6; 7-8 ...
