Rate of Sn1 rxn

JEE Main 2015 Tutorials › Organic Chemistry questions › Rate of Sn1 rxn

Its a highly silly doubt....I know weaker bases are better leaving groups what if the leaving group is the same, then which of the two orgainc compunds would give a faster rxn ?
for example :- which out of the following two would give a faster sn1 rxn
Isoprolybromide or Isobutylbromide?

most probably,bulky groups present on nucleophilic centre might form less stable carbocation due to steric effect .thus, isopropyl bromide would hv a faster SN1 rkn.

yes in SN1 reactions the reaction is governed by factor of steric hindrance so isopropyl bromide would give a faster reaction
