JEE Main Chemistry Test- 9 - Question 16
Save

Consider the following sequence of reactions
The final product (B) is

Detailed Solution: Question 16

B is correct. The Grignard reagent CH3MgBr adds to the carbonyl carbon and, after acid workup with H3O+, gives the secondary alcohol CH3CH(OH)CH3 (A).

CH3CHO + CH3MgBr → (H3O+) → CH3CH(OH)CH3

Oxidation of a secondary alcohol with K2Cr2O7 converts it into the corresponding ketone. Thus CH3CH(OH)CH3 is oxidised to CH3COCH3 (B).

CH3CH(OH)CH3 + [O] → CH3COCH3 + H2O

Therefore, the final product B is CH3COCH3; choose option B.
