How Esther Bounced Back From a “C” To Get A’s In Organic Chemistry 1 And 2
The importance of attitude The student who is the subject of today’s success story, Esther, didn’t start off doing well in organic chemistry. Actually, she

What Factors Affect Free-Radical Stability? In the last article we introduced free radicals – neutral, electron-deficient chemical species with a partially filled orbital – and
Read moreBond Strengths And Radical Stability
Bond Dissociation Energies And Radical Stability The last article discussed factors which stabilize – and destabilize – free radials. So how do we quantify free-radical
