Firstly, the reactivity order of SN1 is 3°>2°>1°
Here isopropyl chloride is 2°, propyl chloride is 1°, ethyl chloride is 1° and methyl chloride is also 1°.
As in SN1 reaction first step is formation of carbocation.
The stability of carbocation will be propyl carbocation > ethy carbocationl > methyl carbocation by the analysis of hyperconjugation and inductive effect.
Hence, the order of reactivity to SN1 will be as isopropyl chloride> propyl chloride> ethyl chloride>methyl chloride.
