The photo dimerization of benzophenone to benzopinacol is a net hv OH Ph Ph λ = 4 Ph Ph OH Ph Ph a. reduction b. not a redox c. oxidation of the carbons in benzophenone going to benzopinacol? 4 Andrea Salas Rivera AS く The photo dimerization of benzophenone to benzopinacol is initiated by what type of electronic transition that then rapidly decomposes to a diradical since putting in electrons in anti bonds breaks bonds! The diradical then starts abstracting hydrogens from solution as pictured in the text? σ = electrons in sigma bonds n = electrons in non-bonding orbitals π = electrons in pi bonds = anti bonds Hint: This process is very important because although the molecule responsible for human vision (retinal) is not a very long conjugated pi system, this transition allows retinal to absorb visible light. a. n to σ* ○ b. σ to σ* ○ с. п tо π d. n to π* e. σ to П* f. П to σ* Although the photo dimerization of benzophenone to benzopinacol is only possible because the carbonyl of benzophenone is conjugated to phenyl groups, other carbonyl compounds can be dimerized to a pinacol product using metals in the absence of a proton source until the hydronium workup. 2 R R OH R R ? Na R R OH Knowing the oxidation state difference of this reaction, what is the coefficient of the sodium in the above reaction? Whole number answer, no units. Answer:
