The molecule 2-butene, C4H8, can undergo a geometric change called cis-trans isomerization. (Figure 1) Such transformations can be induced by light and are the key to human vision. Rotation about the C=C bond, which breaks the π bond, is required for the isomerization. The average bond energy (enthalpy) for a C=C double bond is 614 kJ/mol and that of a C−C single bond is 348 kJ/mol. Estimate the energy needed to break only the π bond of the double bond of 2-butene.Express your answer numerically in joules per molecule.

3. Carbon atoms will bond with each other to form a chain, often with the peripheral atoms being hydrogen. These compounds, hydrocarbons, are organic compounds composed only of carbon and hydrogen. However, when hydrogen atoms are substituted with other elements, such as fluorine, this changes the properties of the molecule. Methylfluoride (CH3F), a substituted hydrocarbon, is used in semiconductor processing. Figure 1 depicts an incorrect Lewis structure for CH3F. (QUestion shown in photo) Which reason best explains why this structure is incorrect? a) Hydrogen lacks an octet. b) Too few electrons are used. c) Carbon cannot exceed an octet. d) Fluorine atom has too many electrons.
