Which of the following is not formed in iodoform reaction?

Options

  1. AC H 3 C O C H 2 I
  2. BI C H 2 C O C H 2 I
  3. CC H 3 C O C H I 2
  4. DC H 3 C O C I 3

Correct answer

B. I C H 2 C O C H 2 I

Step-by-step solution

Halogenation of ketones or aldehydes takes place in α -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.
