An ester (A) with molecular formula C ₉ H ₁₀ O ₂ was treated with excess of CH ₃ MgBr and the compound so formed was treated with conc. H ₂ SO ₄ to form olefin (B). Ozonolysis of B gav ketone with formula C ₈ H ₈ O . Which shows positive iodoform test the structure of A is :

Options

  1. ACH ₃ CH ₂ COC ₆ CH ₅
  2. BC ₆ H ₅ COOC ₂ H ₅
  3. CC ₆ H ₅ COOC ₆ H ₅
  4. DCH ₃ COC ₆ H ₄ COCH ₃

Correct answer

B. C ₆ H ₅ COOC ₂ H ₅

Step-by-step solution

Only C ₆ H ₅ COOC ₂ H ₅ corresponds with the molecular formula of the ester A . Further it explains all the given reactions.
