Identify the compound obtained in following reaction?
Show Hint
In multi-step aromatic transformations, always keep track of whether the group is substituting on an aliphatic side-chain or directly modifying the aromatic core (Ar group) to rule out mismatched option sets instantly!
Step 1: Read the scheme.
The reaction shown takes an aryl starting material through a substitution or coupling step on the ring. We follow the standard route for this kind of conversion.
Step 2: Decide the product type.
The reagents in the given sequence point to the structure drawn in option 4 rather than a simple aryl chloride, an ether, or the other choices.
Step 3: Conclude.
The final compound matches the structure in option 4.
\[ \boxed{\text{Compound in option 4}} \]
