Styrene on reaction with reagent X gave Y which on hydrolysis followed by oxidation gave Z . Z gives positive 2,4 - DNP test but does not give iodoform test. What are X and Z respectively?

Options

  1. AHBr ; C ₆ H ₅ CO CH ₃
  2. BHBr ; C ₆ H ₅ CH ₂ CHO
  3. CHBr / ( C ₆ H ₅ CO )₂ O ₂ ; C ₆ H ₅ CH ₂ CHO
  4. DHBr / ( C ₆ H ₅ CO )₂ O ₂ ; C ₆ H ₅ CO CH ₃

Correct answer

C. HBr / ( C ₆ H ₅ CO )₂ O ₂ ; C ₆ H ₅ CH ₂ CHO

Step-by-step solution

2, 4- DNP test given by both aldehyde and ketones So a and d option eliminated.
