(II) < (I) < (III)
(I) < (III) < (II)
(II) < (III) < (I)
(III) < (II) < (I)
Forklaring
Since SN1 reactions involve the formation of carbocation as intermediate in the rate
determining step, more is the stability of carbocation higher will be the reactivity of alkyl
halides towards SN1 reaction.

Hence correct order is II < I < III.
Hence correct order is II < I < III.
