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?
- A \(\mathrm{HBr} ; \mathrm{C}_6 \mathrm{H}_5 \mathrm{CO} \mathrm{CH}_3\)
- B \(\mathrm{HBr} ; \mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{CHO}\)
- C \(\mathrm{HBr} /\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CO}\right)_2 \mathrm{O}_2 ; \mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{CHO}\)
- D \(\mathrm{HBr} /\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CO}\right)_2 \mathrm{O}_2 ; \mathrm{C}_6 \mathrm{H}_5 \mathrm{CO} \mathrm{CH}_3\)
Answer & Solution
Correct Answer
(C) \(\mathrm{HBr} /\left(\mathrm{C}_6 \mathrm{H}_5 \mathrm{CO}\right)_2 \mathrm{O}_2 ; \mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{CHO}\)
