  • Use reciprocal precipitate time to compare hydrolysis rates in aqueous ethanol.
  • Identify AgCl, AgBr or AgI from white, cream or yellow precipitate formation.
  • Compare structural class and C–X strength as separate reasons for different rates.

Edexcel A-Level Chemistry AS 10.10 Experimental Observations and Data Can Be Used to Compare the Relative Rates of Hydrolysis of I Primary Secondary Questions question 1

[Maximum number: 1]

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 what would be measured in the experiment to compare the rates of hydrolysis.
