The rate of solvolysis for the following tertiary halides in 80% aqueous ethanol at 25°C follows the order:
Compound $X$ gives alcohol $P$ as the major product for the reaction: \;i) CH$_3$MgBr ii) H$_3$O$^+$. Suitable option(s) for $X$ is/are. ($P$ is the benzylic tertiary alcohol bearing two CH$_3$ groups)
Compounds P and Q undergo E2 elimination with reaction rate constants of \(k_1\) and \(k_2\), respectively, as shown below. Which is/are the CORRECT option(s)?
