Chapter 26.8, Problem 28CC
Interpretation Introduction
Interpretation:
A mechanism for biosynthesis of
Concept introduction:
Terpenes are constructed from dimethylallyl pyrophosphate and isopentenyl pyrophosphate. In the synthesis of terpene pyrophosphate is the leaving group as it is a weak base. Nucleophilic attack happens to form another carbocation. Finally proton transfer happens to give the final product.
The terpene synthesis involves the following steps,
- Loss of OPP (pyrophosphate group)
- Nucleophilic attack
- Deprotonation
The above three steps are repeated again and again. In each step and isoprene unit is added more. Finally to obtain
To draw: a mechanism for the given transformation.

If the uncertainty in delivering H2SO4 is ±0.01 mL, calculate the absolute uncertainty in the molarity (0.110 M). Assume there is negligible uncertainty in the formula mass of H2SO4 and in the final volume (2.000 L) and assume random error.arrow_forwardDon't used hand raiting and don't used Ai solutionarrow_forward
