Question
Chapter 16, Problem 16.61P
Interpretation Introduction
Interpretation: The mechanism for the biological conversion of linalyl diphosphate to limonene is to be drawn.
Concept introduction: In biological reactions, allylic carbocations are the intermediates that are required for the formation of limonene.
The general steps involved in the biological formation of limonene are stated below.
• The first step is the generation of allylic carbocation by the loss of the diphosphate group.
• The second step is the formation of six-membered ring.
• The third step is the deprotonation to give final product.

A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
