Reactions Of Halogenoalkanes 1 Chemsheets Answers Exclusive [2021] -

Halogenoalkanes undergo nucleophilic substitution with aqueous alkali, ethanolic potassium cyanide, and ammonia to form alcohols, nitriles, and primary amines, respectively. Additionally, elimination reactions occur with hot ethanolic KOH to produce alkenes, with reactivity increasing in the order C-Cl < C-Br < C-I. For the full resource, visit Chemsheets.

Bond Enthalpy: The rate of reaction is primarily determined by the strength of the bond rather than its polarity. Trend: Reactivity increases as you go down the group: . Iodoalkanes react the fastest because the bond is the weakest. Expert Perspectives & Study Tips reactions of halogenoalkanes 1 chemsheets answers exclusive

• Mechanism: First ionization to form a carbocation (same intermediate as SN1), then a base removes a proton to give an alkene.
• Kinetics: Rate = k[RX].
• Favoured by: Tertiary substrates, weak bases, polar protic solvents, higher temperatures.
• Competes with SN1 since both share a carbocation intermediate.

5. Reaction Rates and Silver Nitrate Test

Chemsheets often includes a task linking bond enthalpy to reaction rates. Mechanism: First ionization to form a carbocation (same
