During nucleophilic substitution reactions, the carbon-halogen bond undergoes heterolytic fission and a new covalent bond is formed between carbon and the nucleophile.
(1) Draw a diagram to show the formation of a bond between a halogenoalkane and a nucleophile. Use curly arrows to represent the movement of the electrons. Use Nu: to represent the nucleophile.
(2) What name is given to the type of covalent bond formed during the reaction?
