Below is the UV-vis spectrum for the experimental product List the ma peak that corresponds to the n * electronic transition 350 400 450 500 550 250 300 340 0.8511 A 61 Pace c. Rationalize the differences in the max values in parts a and b

Aldol condensation Experiment

Answer 1

6. apht nytt tramition with high amax value and a lower intense transition that lower ton value of fie absorption son prou coefficient. 4 transition corresponds to amax tata A +0.294 $0, and on as to higher amax the n th transition corresponds to higher smat very low intensity transition so the amax near 250 nm in the and spectrum corresponds to nyri transition
