Chapter 20, Problem 92CP

Interpretation Introduction

Interpretation: For the given formation of epoxide and bromohydrin, a plausible mechanism has to be provided.

Concept Introduction:

 For any given transformation, the following mandatory observations have to be made clear to predict the synthetic scheme:

• Observe whether there is any change in the carbon skeleton.
• Observe whether there is any change in the location of the functional group.
• Predict the synthetic scheme in such a way that these two observations have to be achieved within the minimum chemo selective steps.

The given transformation is:

S_N2 reaction:

The alcohols is reaction with acids like hydrochloric acid or hydrobromic acid, the bromine atom attacks back side of the carbon atoms which is bearing alcohol group which yield the corresponding inversion product.
