Which of the following will give positive iodoform test?

Options

AHCHO
BCH ₃ OCH ₃
C( CH ₃ )₂ CO
DCH ₃ CH ₂ Cl

Correct answer

C. ( CH ₃ )₂ CO

Step-by-step solution

The compounds which contain either group exhibit positive iodoform test. ( CH ₃ )₂ CO due to presence of CH ₃- C = O group gives positive iodoform test aligned & H ₃ C & H ₃ C & C = O + NaOH + I ₂ & CHI ₃ &+ CH ₃ COONa + H ₂ O aligned
