Under certain conditions, when \((R)-2\) -bromobutane is heated with water, the \(S_{N} 1\) substitution proceeds twice as fast as the \(S_{N} 2\). Calculate the e.e. and the specific rotation expected for the product. The specific rotation of \((R)\) -butan-2-ol is \(-13.5^{\circ}\). Assume that the \(S_{N} 1\) gives equal amounts of the two enantiomers.
