If you are working through the task sheet, you’ve likely realized that halogenoalkanes (also known as haloalkanes) are the gateway to organic synthesis. Their reactivity is defined by one simple feature: the polar C-X bond . Their reactivity is defined by one simple feature:

R-X + Ag⁺ (from AgNO₃) + H₂O → R-OH + AgX(s) + H⁺ | Reaction | Reagent(s) | Conditions | Product

: These reactions occur in two steps and involve the formation of a carbocation intermediate, similar to SN1 reactions. However, instead of a nucleophile attacking the carbocation, the carbocation loses a proton to form an alkene.

| Reaction | Reagent(s) | Conditions | Product Type | Mechanism | |---|---|---|---|---| | Hydrolysis to alcohol | NaOH(aq) or KOH(aq) | Warm, aqueous | Alcohol (ROH) | SN1 or SN2 | | Water hydrolysis (slow) | H₂O + AgNO₃ (test) | Warm ethanol/water | Alcohol + AgX | SN1 | | Cyanide addition | KCN in ethanol | Warm | Nitrile (RCN) | SN2 | | Amine formation | Excess NH₃ in ethanol | Pressure, heat | Primary amine (RNH₂) | SN2 | | Elimination | NaOH in ethanol | Heat under reflux | Alkene | E1 or E2 | | Identification | AgNO₃ in ethanol | Warm | Silver halide precipitate | Hydrolysis then precipitation |

By memorizing that sentence, you will never miss a question on “Reactions of Halogenoalkanes 1.”
