Summary of Methods for Preparing Alcohols

So far, we have seen many ways to make alcohols. We can make primary, secondary, or tertiary alcohols through a variety of methods. As a review, identify the reagents necessary to accomplish each of the following transformations  

EXERCISE 12.50 Using any reagents of your choice, show three different ways of preparing the following alcohol  

ANSWER This is a secondary alcohol. We have seen many ways to make secondary alcohols. We can start with a ketone, and reduce with LAH or NaBH4  

we can start with an aldehyde, and perform a Grignard reaction  

Or we can start with an aUcene and perform an addition (acid-catalyzed hydration)
