Compound ' P ' undergoes the following sequence of reactions : ' P ^ is :

Step-by-step solution

The final product is cyclohexyl isocyanide ( C₆H₁₁NC ). Working backwards from the final product: The last step involves CHCl₃ and KOH (alc), which is the Carbylamine reaction. This reaction converts a primary amine ( R-NH₂ ) into an isocyanide ( R-NC ). Thus, the intermediate before this step must be cyclohexylamine ( C₆H₁₁NH₂ ). The step before cyclohexylamine involves Br₂ and KOH , which is the Hoffmann Bromamide Degradation reaction. This reaction converts an amide ( R-CONH₂ ) into a primary amine ( R-NH₂ ) wit
