Use Woodward-Feiser rules to match the given organic compounds with their 279 nm 1. 2.

please help solve all.  i keep gettting them wrong

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* C. π το π d. n to П e. σ to П* f. π to σ'
