Vedclass · Answer

(B) The reaction of a ketoxime with an acid catalyst like $H_2SO_4$ is known as the $	ext{Beckmann rearrangement}$.
In this reaction,the group anti to the hydroxyl $(-OH)$ group on the nitrogen atom migrates to the nitrogen,followed by the addition of water and tautomerization to form an amide.
The starting material is a ketoxime. Upon treatment with $H_2SO_4$,the $-OH$ group is protonated and leaves as water,creating a nitrenium ion intermediate. The alkyl group (decalin ring) migrates to the nitrogen,and subsequent attack by water followed by tautomerization yields the corresponding amide,$N$-(decalin$-1-$yl)acetamide.
Therefore,the correct product and reaction name are $N$-(decalin$-1-$yl)acetamide and $	ext{Beckmann rearrangement}$ respectively.

Identify the product and the name of the reaction for the following transformation:
$
\begin{array}{c}
\text{Decalin-1-one oxime} \rightarrow{H_2SO_4} \text{Product}
\end{array} $
(The starting material is a ketoxime derived from decalin$-1-$one with a methyl group at the alpha position).
