Question

Consider the given reaction, the major product among the following is:

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is C

Explanation for correct option:

C

1. Aromatization: It is a chemical system in which an aromatic compound is formed from a non-aromatic precursor.
2. In the given reaction, reactant reacts with $\mathrm{Zn}-\mathrm{Hg}/\mathrm{HCl}$ to form ethylbenzene. This reaction is Clemenson reduction
3. The above product formed undergo cyclization under the action of ${\mathrm{Cr}}_2{\mathrm{O}}_3$ to form the required aromatic compound.
4. The reaction can be presented as follows:

Hence option C is correct, in aromatization of 4-ethylhexan-3-one the product formed is ethyl benzene.
