Whether the given ester will form micelles in water is to be explained. Concept introduction: Micelles are formed by molecules with a hydrophilic group at one end and a hydrophobic group at the other end. The hydrophobic ends tend to interact with each other through induced dipole-induced dipole interactions. Thus, they can gather in an approximately spherical aggregate with the polar groups exposed on the surface, where the polar group can be solvated by the surrounding water molecules. However, the polarity of this group must be sufficiently strong for the high solvation needed for the formation of stable micelles. This requires strong ion-dipole interactions, and therefore a polar group that is ionic in nature.

A. Provide a stepwise mechanism for the formation of nerolidyl pyrophosphate fromfarnesylpyrophosphate B. Provide a stepwise mechanism for the formation of carbocation 1 from nerolidylpyrophosphate. Number the backbone carbons of nerolidyl pyrophosphate from 1 to 11 as shown, andinclude the carbon numbering in your structure of 1 C. Following from B, give an arrow-pushing mechanism to convert 1 to 2 and 2 to 3. Use thebackbone carbon numbering from 1 to indicate where carbon atoms ended up in 2 and 3 D. In addition to forming epi-cedrol, carbocation 3 gives three minor byproducts: a diastereomericalcohol and two alkenes. Draw mechanisms that could give rise to these three products
