When 1-phenyl ethanone is reacted with propylamine, propyl group gets attached to the carbonyl carbon by removing water molecule. So, the product formed is given below:

Product (a)

When acyl chloride is reacted with pyrrolidine, this pyrrolidine gets substituted in the place of chlorine in acyl chloride. Pyrrolidinium ion is also formed as a minor product. Thus, the products formed are shown below:

Product (b)

When aniline is reacted with $\mathrm{HCl}$and sodium nitrite, it forms benzene diazonium chloride. This undergoes Sandmeyer reaction. In this reaction, the reagents are ${\mathrm{H}}_2\mathrm{O}$, ${\mathrm{Cu}}_2\mathrm{O}$and$\mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_2$ . It gives phenol as product. The product is shown below:

Product (c)

When 1-phenyl ethanone is reacted with N-ethyl ethanamine, the double bond between carbon and oxygen gets shifted to the $\mathrm{C}−{\mathrm{CH}}_3$bond and N-ethylethanamine gets added to this carbon atom. Thus, the product formed is shown below:

Product (d)
