β1-bromopropane is heated with NaOH(aq) and separately with NaOH in ethanol. State the major product in each case and explain.β
) because halogens are more electronegative than carbon. This makes the carbon atom susceptible to attack by βspecies that donate an electron pair to form a new covalent bond. A. Reaction with Aqueous NaOH (Hydrolysis) Reagent: Sodium hydroxide ( NaOHcap N a cap O cap H ) or Potassium hydroxide ( KOHcap K cap O cap H Conditions: Aqueous, warm/under reflux.

For primary halogenoalkanes, the mechanism generally follows these steps: The nucleophile ( ) attacks the CΞ΄+cap C raised to the delta plus power from the side opposite the halogen. A transition state forms where the bond is forming while the bond is breaking. The halide ion ( Xβcap X raised to the negative power ) leaves (the "leaving group"). 5. Elimination Reactions 5.
