Options

  1. ACH3COCH2IC{H}_{3}COC{H}_{2}I
  2. BICH2COCH2IIC{H}_{2}COC{H}_{2}I
  3. CCH3COCHI2C{H}_{3}COCH{I}_{2}
  4. DCH3COCI3C{H}_{3}COC{I}_{3}

Correct answer

B. ICH2COCH2IIC{H}_{2}COC{H}_{2}I

Step-by-step solution

Halogenation of ketones or aldehydes takes place in α\alpha -position. Further presence of halogen on a carbon atom increases acidity of that particular carbon atom, hence further halogenation takes place on the carbon having halogen and not on other carbon atoms.
