Problem 18-20

What is the advantage of a time-resolved emission measurement with Eu3 versus measurement of fluorescence from organic chromophores?

Step-by-Step Solution:
Step 1 of 3

Organic Chemistry – Ch. 14 (Conjugated Systems) • Intermediates and course of reactions (overview) o Neutral compounds: cations, radicals, anions o Mechanism: flow of electrons, indetifying charges • Conjugation o Double bonds affect the properties of attached groups that contain unhybridized p orbitals or  bonds o Three or more adjacent p orbitals constitute a conjugated  system ▪ The simplest conjugated system is the allylic system (three carbons –  bonds – with one double bond) • Overlap of three adjacent p orbitals: electron delocalization in the 2- propenyl (allyl) system o Delocalization stabilizes 2-propenyl (allyl) intermediates ▪ In each o
