The correct order of rate of solvolysis for the following compound is 
I 
II 
III
I II III(a)$\mathrm{III} > \mathrm{II} > \mathrm{I}$
(b)$\mathrm{II} > \mathrm{I} > \mathrm{III}$
(c)III $>$ I $>$ II
(d)$\mathrm{II} > \mathrm{III} > \mathrm{I}$
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
7-Bromocycloheptatriene ionises readily to the aromatic tropylium ion (II). Benzyl bromide (III) comes next. 5-Bromocyclopentadiene (I) would give the antiaromatic cyclopentadienyl cation. II > III > I (d).
