Following are the observed relative rates for the conversion of alkyl halides in ethanol to the respective alcohols. Relative rates (unassigned among a primary bromide, a secondary (allylic/benzylic) bromide reacting by , one reacting by a mix of /, and a highly hindered bromide reacting by ).

What is the value of the relative reaction rate for ethyl bromide?

Answer: 200

Solution

Among the four relative rate values, the reaction proceeding purely by with minimal steric hindrance (a primary, unbranched system) corresponds to the fastest of the -type rates, while the most hindered tertiary-type system reacting by is assigned the overall fastest value (2000) due to the highly
