Question

Compound a has molecular formula c5h10. hydroboration-oxidation of compound a produces 2-methylbutan-1-ol. draw the structure of compound a:

Answer 1

To help you answer this question, you can search a sample reaction in the internet for hydroboration-oxidation. Take a look at the attached picture. The sample reaction is shown at the top. We can deduce that the original compound must be an alkene. Following the pattern, compound a must be 2-methylbutene as shown in the picture.

Answer 2

The structure of compound that has general formula ${{\mathbf{C}}_{\mathbf{5}}}{{\mathbf{H}}_{{\mathbf{10}}}}$ and leads to the formation of 2-methylbutan-1-ol is attached in the image.

Further explanation:

Hydroboration-Oxidation is a two-step pathway used to produce alcohol. The reaction proceeds in a manner, where the hydrogen attaches to carbon that is more substituted and the boron attach to the least substituted carbon in the alkene double bond. The borane serves as a lewis acid by accepting two electrons from an alkene. This process completes octet of boron. Also,this process does not require any activation by a catalyst. The hydroboration oxidation mechanism has the elements of both hydrogenation and electrophilic addition.

Hydroboration oxidation reaction involves two steps given as follows:

1. In the first step, borane is added to alkene to form alkyl borane. This step is called as hydroboration of alkene.

2. In the next step, alkyl borane reacts with hydrogen peroxide and sodium hydroxide to form alcohol. This step is known as oxidation.

Given, 2-methylbutan-1-ol is formed by alkene having general formula ${{\text{C}}_{\text{5}}}{{\text{H}}_{{\text{10}}}}$. The given alcohol is formed by alkene through hydroboration oxidation reaction. The alkene having general formula ${{\text{C}}_{\text{5}}}{{\text{H}}_{{\text{10}}}}$ and that leads to the formation of 2-methylbutan-1-ol must be 2-methylbutene.

The mechanism of the formation of 2-methylbutan-1-ol is attached in the image.
