24/4 C6 Plus Cmp Rl/bx 1m Bl

exercise 2.21 i'll write the electron configurations of b2 plus b2 minus c2 minus and f2 plus so let's look at be2 plus first uh you need to use this figure 2.17 in the book this is figure 2.17 you need to find a be2 neutral first and then its electron configuration is one sigma g2 one sigma u2 therefore for b2 plus what you need to do is just remove one electron so we're going to just write this done uh the homo es1 sigma u so we'll just draw the homo the homo has a nodal surface that's be2 plus now i'm going to look at f2 plus uh again you need to look at this figure 2.17 you find f2 uh this f2 plus is simply f2 minus one electron so you remove one electron from the one pi g orbital and therefore the electron configuration for f2 is simply one sigma g two one sigma u two two sigma g two one pi u four one pi g three i'll put this three in the superscript uh maybe i should go over one m
