Question

The increasing order of the reactivity of the following halides for the SN1 reaction is : (A) (I) < (III) < (II) (B) (II) < (III) < (I) (C) (III) < (II) < (I) (D) (II) < (I) < (III)

Rate of SN1 reaction propto stability of carbocation So, II < I < III Increase stability of carbocation and hence increase reactivity of halides.

Q. The increasing order of the reactivity of the following halides for the $S_{N} 1$ reaction is :

(I) < (III) < (II)

(II) < (III) < (I)

(III) < (II) < (I)

(II) < (I) < (III)

Rate of $S_{N} 1$ reaction $\propto$ stability of carbocation
So, II < I < III

Increase stability of carbocation and hence increase reactivity of halides.
