Question
Consider the following organic reaction sequence. Choose the final product from the following (consider the major product in all intermediate reactions)
Choose an option
Show full solutionCorrect option: A
Correct answer
ABenzene
Step-by-step explanation
The starting material is propanoic acid ().
In step (i), propanoic acid reacts with upon heating to form propanamide.
In step (ii), propanamide undergoes Hoffmann bromamide degradation with and to form ethylamine.
In step (iii), ethylamine reacts with nitrous acid () to form an unstable diazonium salt, which hydrolyzes to give ethanol.
In step (iv), ethanol reacts with benzenediazonium chloride (). Ethanol reduces the diazonium salt to benzene, while getting oxidized to ethanal.
The final major product (X) is benzene.
