Zadanie 4a
Reactions of halogenoalkanes with hydroxide ions are an example of nucleophilic substitution. Deduce the equation, showing the movement of electrons with curly arrows, for the reaction of 1-chloropropane with aqueous potassium hydroxide.
Nucleophiles
Define a nucleophile as a species that donates both bonding electrons to form a bond with an electrophile, and recognise neutral and negatively charged nucleophiles such as OH-, CN-, NH3 and H2O by their lone pairs.
