By which of the following methods alcohol can be prepared in excellent yield (a) from alkenes(b) by hydroboration-oxidation (c) from carbonyl compounds
(d) from Grignard reagent
Dear student,
Hydration of alkene gives alcohol.
Hydroboration-oxidation of alkene gives alcohols and in this reaction, stereochemistry is preserved. In this process, the alkene is treated with diborane, and the product obtained is oxidized with alkaline hydrogen peroxide, this gives the highest yield among given reactions.
The reduction of carbonyl compounds gives alcohols but the yield is not so good, we may not get our desired product.
To produce primary alcohol, the Grignard reagent is reacted with formaldehyde, in all other cases, we didn't get the primary alcohols.
Hence, the correct option is (b).
Regards
