As you move down Group 7, the halogen atoms get larger. The shared pair of electrons is further from the nuclei, making the bond longer and weaker. Bond Enthalpy ( kJ mol-1kJ mol to the negative 1 power Reactivity C-F Extremely unreactive (strong bond) C-Cl Moderately reactive C-Br C-I Highly reactive (weakest bond) Key Takeaway: Even though the

The carbon-halogen bond breaks heterolytically, and the halogen departs as a halide ion ( X−X raised to the negative power 2. Key Nucleophilic Substitution Reactions
When drawing your mechanisms for these answers, remember the "Golden Rules": must start from a lone pair or a bond. Include dipoles ( δ+delta plus δ−delta minus ) on the C-X bond. In conclusion, the reactions of halogenoalkanes are a
