How would you distinguish between \({ S }_{ N }1\) and \({ S }_{ N }2\) mechanisms of substitution reactions? Give one example of each.

Compound 'A' with molecular formula C₄H₉Br is treated with aq. KOH solution. The rate of this reaction depends upon the concentration of the compound 'A' only. When another optically active isomer 'B' of this compound was treated with aq.  KOH solution, the rate of reaction was found to be dependent on concentration of compound and KOH both.
