sigma bond   single covalent bond formed when an electron pair is shared by direct overlap of bonding orbitals  
pi bond   bond that is formed when parallel orbitals overlap to share electrons  
endothermic reaction   chemical reaction or process in which a greater amount of energy is required to break existing bonds in the reactants than is released when new bonds from in product molecules
