Chapter 8, Problem 91IP

Interpretation Introduction

Interpretation:

From the given reactions, an efficient method to synthesis given alcohol has to be predicted.

Concept Introduction:

• Simple hydration in acidic media gives the addition product through carbocation intermediate and follows Markovnikov addition.
• An acid-catalysed hydration is shown below.

  

• Markovnikov’s rule: An unsymmetrical alkene reacts with hydrogen halide in which halide ions goes to the more substitution position of carbon-carbon double bond which provides alkyl halides.

• Hydroboration-oxidation reaction: Addition of $\text{–H and –OH}$ group across the double bond in presence of borane and hydrogen peroxide with base is known as hydroboration-oxidation reaction.  It follows Anti-Markovnikov addition.

• Anti-Markovnikov’s rule: In the presence of per acid, an unsymmetrical alkene reacts with hydrogen halide in which halide ions goes to the less substitution position of carbon-carbon double bond which provides alkyl halides.
