Draw a structural formula for the alkene you would use to prepare the alcohol shown by hydroboration/oxidation.
Nastasia [14]

Answer:

See explanation

Explanation:

The question is incomplete because the image of the alcohol is missing. However, I will try give you a general picture of the reaction known as hydroboration of alkenes.

This reaction occurs in two steps. In the first step, -BH2 and H add to the same face of the double bond (syn addition).

In the second step, alkaline hydrogen peroxide is added and the alcohol is formed.

Note that the BH2 and H adds to the two atoms of the double bond. The final product of the reaction appears as if water was added to the original alkene following an anti-Markovnikov mechanism.

Steric hindrance is known to play a major role in this reaction as good yield of the anti-Markovnikov like product is obtained with alkenes having one of the carbon atoms of the double bond significantly hindered.

How many moles of hydrogen are in 3.0 moles of C6H12O6?
tangare [24]
<h3>Answer:</h3>

              36 moles of Hydrogen

<h3>Solution:</h3>

The molecular formula of Glucose is,

                                                 C₆H₁₂O₆

As clear from molecular formula, each mole of Glucose contains 12 moles of Hydrogen atoms.

Therefore,

                 1 mole of C₆H₁₂O₆ contains  =  12 moles of Hydrogen

So,

       3.0 moles of C₆H₁₂O₆ will contain  =  X moles of Hydrogen

Solving for X,

                        X =  (3.0 mol × 12 mol) ÷ 1 mol

                        X  =  36 moles of Hydrogen
