In the following reactions, $\mathbf{P}, \mathbf{Q}, \mathbf{R}$, and $\mathbf{S}$ are the major products.




The correct statement about $\mathbf{P}, \mathbf{Q}, \mathbf{R}$, and $\mathbf{S}$ is :

KI in acetone, undergoes S_N2 reaction with each of P, Q, R and S. The rates of the reaction vary as

The major product of the following reaction is:

Statement 1 : Bromobenzene upon reaction with Br$$_2$$/Fe gives 1, 4-dibromobenzene as the major product.

and

Statement 2: In bromobenzene, the inductive effect of the bromo group is more dominant than the mesomeric effect in directing the incoming electrophile.
