Problem P9E.1

Set up and solve the Hückel secular equations for the \(\pi\) electrons of the triangular, planar \(\mathrm{CO}_{3}^{2-}\)ion. Express the energies in terms of the Coulomb integrals \(\alpha_{0}\) and \(\alpha_{C}\) and the resonance integral \(\boldsymbol{\beta}\). Estimate the delocalization energy of the ion.

CHEMISTRY 1211 Sara Blankenship Tuesdays – Thursdays 3:30-4:45 FIRST EXAM- -names & symbols for elements in 1 5 periods of periodic table -formulae & names for common polyatomic ions (table 2.4.1) -formulae & common names of small molecules (tables 2.3.3 & 2.3.4) 1 CLASS: 8.15.17 (Tuesday) Chapter 1: learning objectives- -DEFINE Chemistry -identify states of matter -dimensional analysis -significant figures & their importance Heterogeneous- different throughout Homogeneous- mixed completely, everything the same throughout Examples: Air- Heterogeneous (air different on top of mountain v. base of mountain) Black Coffee- Homogeneous Hard Drive- Heterogeneous Super Saturated Sugar Solution- Heterogeneous NaCl- Heterogeneous Measurements can be… -accurate & precise (all the darts landing in same area, on the target) -precise but not accurate (golf balls all landed in same area, but not near the hole) -neither precise nor accurate (all the points scattered and not near target) 2ND CLASS: 8.17.17 (Thursday) 1. Minutes per month (60 x 24 x 365) / 12 = 43800 minutes/month 2. 24hrs/day, 60 mins/hr, 7 days/week, 4 weeks/month – minutes/perfect month (60 x 24 x 7 x 4) = 40320 3. answers same or different Different 4. which answer is better 1 because not every month has 4 weeks in it. 1 one accounts for the 365 days in a year. 5. Driving 70mph and take eyes off road for” just a second”. How many miles traveled How many feet *sig figs* 70 / 60 / 60 = .0194 miles & 102.6 feet // w/ sig figs- .02 miles & 100 feet Chapter 2: elements and
