What is an alkene and its general formula? It is an unsaturated hydrocarbon with a least one C=C bond. General formula is CnH2n What is a sigma bond? σ single covalent bond formed when two s orbitals overlap. High electron density What is a pi bond? sideways overlap of p orbitals that occur in a double or triple bond. Much weaker than sigma, low bond enthalpy and lower electrostatic attraction Is an alkane or an alkene more reactive? Alkene. contains both sigma and pi bonds with high ele...

What are saturated vs unsaturated fatty acids? correct answer: •Saturated fatty acids have no C=C bonds (their C's have max # of Hs) •Unsaturated fatty acids have one or more C=C bonds (monosaturated = one double bond) (polyunsaturated = more than 1 double bond) •Z (cis) are naturally occurring double bonds; E (trans) are artificial double bonds How is biodiesel produced commercially? Which method is predominant? correct answer: ***1) Base catalyzed transesterification of oil with ...
