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
- ACH ₃ CH ₂ COC ₆ CH ₅
- BC ₆ H ₅ COOC ₂ H ₅
- CC ₆ H ₅ COOC ₆ H ₅
- 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.
