Question

Show how you would prepare monodeuteriocyclohexane (C6H11D) from bromocyclohexane (C6H11Br) using an organometallic reagent.

Answer 1

Answer:

Process of preparation has been given below

Explanation:

• At first, bromocyclohexane is converted to  cyclohexyl magnesium bromide through grignard process
• Secondly, this cyclohexyl magnesium bromide is treated with $D_{2}O$.
• Cyclohexyl magnesium bromide gives an acid-base reaction with $D_{2}O$ by abstracting a deuterium ion.
• Thus, monodeuteriocyclohexane can be prepared
• Reaction scheme has been shown below.
