KI in acetone, undergoes SN2 reaction with each P, Q, R and S. The rates of the reaction vary as
(2013 Adv., Only One Option Correct Type)
Acetone is an aprotic solvent and can dissolve both the nucleophile and the substrate and thus SN2 reaction is Savoured. Also
Thus, reactivity order is S > P > R > Q
The total number of alkenes possible by dehydrobromination of 3-bromo-3-cyclopentylhexane using alcoholic KOH is
(2011, Integer Type)
The substrate has three different types of B—H, therefore, first, three structural isomers of alkenes are expected as
The last two alkenes (II) and (III) are also capable of showing geometrical isomerism hence, two geometrical isomers for each of them will be counted giving a total of five isomers.
The major product of the following reaction is
