IB Chemistry SL/HL - Reactivity 3.4.1 and 3.4.2 - Nucleophiles and Substitution Basics
First Test 2025
A nucleophile is a reactant that forms a bond to its reaction partner (the electrophile) by donating both bonding electrons.
In a nucleophilic substitution reaction, a nucleophile donates an electron pair to form a new bond, as another bond breaks producing a leaving group.
