Draw the Lewis dot structures of the following compounds. In these structures, all atoms are singly bonded and the octet rule is always satisfied. Hints: The structure of a has more than one ring. The structure of b has three six membered rings that share common atoms. In d don't worry about the charge, just put 4 bonds around two of the boron atoms, 3 around the other two. The molecule contains a plane of symmetry.
