1 Nucleophilic substitution of halogenoalkanes.

2 H H H C C H H H H C C H H Br δ+δ+δ-δ- polar +ve centre electronegative

3 NaOH  Na + + OH - O H - Nucleophile Can be –ve or neutral Attracted to a +ve centre

4 H H H C C H H H H C C H H Br δ+δ+δ-δ- H O -

5 H H H C C H H H H C C H H HO -

6 NaOH  Na + + OH - O H - Nucleophile Can be –ve or neutral Attracted to a +ve centre Donates a lone pair to form a dative covalent bond

7 H H H C C H H H H C C H H Br δ+δ+δ-δ- H O - H H H C C H H H H C C H H H O -

8 NaOH(aq) + halogenoalkane Reagent: NaOH(aq) Conditions: Heat and reflux
