| Factor | Primary Halogenoalkane | Tertiary Halogenoalkane | | :--- | :--- | :--- | | | SN2 | SN1 | | Steric Hindrance | Low. Carbon is accessible to nucleophiles. | High. Bulky alkyl groups block attack by nucleophiles. | | Carbocation Stability | Primary carbocations are unstable. | Tertiary carbocations are stable due to +I inductive effect of alkyl groups. | | Reaction with NaOH(aq) | Fast substitution. | Slower substitution (due to steric hindrance), but can eliminate. | 7. Conclusion The Chemsheets resource on reactions of halogenoalkanes primarily assesses the student's ability to distinguish between SN1 and SN2 mechanisms based on structure, predict products based on reagents/conditions, and rationalize reactivity trends using bond enthalpy data. Mastering the polarity of the C-X bond and the stability of the transition states/intermediates is essential for completing the associated tasks. Index Of Dhoom Movie - 3.79.94.248
