  • Rank hydrolysis as iodoalkane faster than bromoalkane faster than chloroalkane.
  • Justify the order using decreasing C–X bond enthalpy rather than polarity or solubility.

Edexcel A-Level Chemistry AS 10.13 Understand in Terms of Bond Enthalpy the Trend in Reactivity of Chloro Bromo and Iodoalkanes Questions question 1

[Maximum number: 2]

This question is about halogenoalkanes.

The rates of hydrolysis of 1-chloropropane, 1-bromopropane and 1-iodopropane in reactions with aqueous silver nitrate solution were compared.

State which of these halogenoalkanes would hydrolyse the fastest. Justify your answer.
