). Excess ammonia prevents the product amine from acting as a nucleophile and undergoing further substitution. 3. Comparing Reactivity: Bond Enthalpy vs. Bond Polarity

1-chloropropane with NH₃.

pathways depending on solvent polarities and nucleophile strengths. 4. Elimination Reactions (Formation of Alkenes)

C–F is the most polar bond, meaning the carbon has the highest charge and should attract nucleophiles fastest.

As the halogen atom increases in size down Group 7, the C-X bond becomes weaker and longer. This is due to the poor orbital overlap between the carbon atom's small 2p orbital and the larger halogen orbitals. reactions of halogenoalkanes 1 chemsheets answers exclusive

Chemsheets often includes a task linking bond enthalpy to reaction rates.

react the fastest because the C-I bond is the weakest and breaks most easily. Rate of Reaction: Iodo > Bromo > Chloro > Fluoro. 4. Key Mechanisms to Know
