Which of the following alkyl halides will undergo SN1 reaction most readily? (i) (CH3)3C−F (ii) (CH3)3C −Cl (iii) (CH3)3C −Br (iv) (CH3)3C −I

This is a multiple choice answer as classified in NCERT Exemplar The Correct Answer is Option (iv). SN1 reactions occur mostly in polar protic solvents such as H2O and follow first-order kinetics. This indicates that the reaction rate is solely determined by one reactant. Because of the great stability of the generated carbocation, this reaction favours tertiary alkyl halides. When a molecule is polarised in water, it generates a carbocation as well as a halide ion. The halides' reactivity is R-I > R-Br > R-Cl > > R-F. As a result, (CH3)3C-I will be the most likely to undergo the reaction.
