Answer #1

Correct Answer:

Option = 3

Explanation:

1) The radical bromination Generally happens on more substituted carbon. Then which is converted into corresponding Grignard reagent by treating with Mg in ether

The formed Grignard reagent react with CO2 gives our target molecule.

2) The keton with 3 alpha hydrogen undergo haloform reaction. The given ketone also have 3 alpha hydrogen so which will undergo haloform reaction in presence of Cl2 and bass and gives our target molecule.
