Reaction of Grignard reagent, with C8H8O followed by hydrolysis gives compound " A " which reacts instantly with Lucas reagent to give compound . The Compound B is :
Options:
Answer:
C
Solution:
C2H5MgBr reacts with C8H8O (acetophenone, C₆H₅COCH₃) to form a tertiary alcohol after hydrolysis.
Product A = C₆H₅C(OH)(CH₃)CH₂CH₃ (2-phenyl-2-butanol).
A reacts instantly with Lucas reagent, confirming that A is a tertiary alcohol.
In Lucas reaction, OH⁻ is replaced by Cl⁻ at the same tertiary carbon.
Therefore B = C₆H₅C(Cl)(CH₃)CH₂CH₃.
This structure matches Option (C).
