Benzofuran is the heterocyclic compound consisting of fused benzene and furan rings. This colourless liquid is a component of coal tar. Benzofuran is the "parent" of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. http://butane.chem.uiuc.edu/anicely/chem102Dfa10/Worksheets/Worksheet14_Hybrid_Key.pdf sight word fluency cards

http://www.chem.ualberta.ca/~vederas/Chem_263/outlines/notes_2009/September_24.pdf WebIn chemistry, pi bonds ( π bonds) are covalent chemical bonds, in each of which two lobes of an orbital on one atom overlap with two lobes of an orbital on another atom, and in which this overlap occurs laterally. Each of these atomic orbitals has an electron density of zero at a shared nodal plane that passes through the two bonded nuclei.
