Ozone formation
Evaluating $\ce{2 O2 -> O3 + O}$ singlet oxygen hypothesis:
The molecule $\ce{O2}$ – also called triplet oxygen – has in its standard state a double bond, but it already is a biradical CH SE: why-...

Ozone formation
The $\ce{O + O2 + M \to O3 + M }$ does appear written as such in many texts and is unusual in that other atom-diatom reactions that have been studied do not seem to need any $M$, such as $\ce{OH + Cl \...

What causes ionisation in redox reactions?
The fundamental mistake you're making here is treating each atom in the reaction as though it's isolated. If you do that, the reaction will make no sense. You have to look at them together.
The energy ...

Why doesn't the reaction between molecule "B" and diethyl oxalate yield a diester?
The enolate of p-chloropropiophenone --namely, B-- is being generated from ketone A by a kinetic base such as lithium diisopropylamide (LDA) in a polar, aprotic solvent, typically tetrahydrofuran (THF)...

Mechanism of ring expansion of epoxide
BF3 facilitates the nucleophilic opening of epoxides by binding to the oxygen. Under its influence the lithium anion of ethoxyacetylene adds at the least hindered sites to both the epoxides opening ...
