Question

Transition-metal catalyzed reactions can involve single-electron transfers to generate these reactive species. For 10 points each:
[10e] Name these reactive species that feature an unpaired electron.
ANSWER: free radicals
[10m] To confirm that a novel reaction involves a radical mechanism, researchers may use this spectroscopic technique to probe for radical species.
ANSWER: electron paramagnetic resonance [or EPR spectroscopy; accept electron spin resonance or ESR]
[10h] A phase-sensitive detector used in EPR spectroscopy performs this operation on the base absorption signal, explaining why common practice in the literature displays this operation of the molecular magnetic susceptibility on the y-axis.
ANSWER: first derivative (with respect to field strength)
