Question

$C{H}_{3}CH=C{H}_2\underset{H_2{O}_2/OH}{\overset{B_2{D}_6}{\to }}$ product X
X is:

• A. $C{H}_3-\underset{OH}{\underset{|}{C}H}-C{H}_{2}D$
• B. $C{H}_3-\underset{D}{\underset{|}{C}}H-C{H}_{2}OH$
• C. $C{H}_3-\underset{OD}{\underset{|}{C}H}-C{H}_3$
• D. None is correct

Answer 1

The correct option is B $C{H}_3-\underset{D}{\underset{|}{C}}H-C{H}_{2}OH$

This is hydroboration oxidation reaction in which a molecule of water is added to the carbon carbon double bond. Since, the diborane contains deuterium, the final product also contains deuterium.
Thus, the final product is the product represented by the option B.
