Br2 + KOH is used in Hoffman's bromide degradation reaction in which amide is converted into primary amine with one C less than the parent amide.

this signifies Y is a primary amine that is also supported by the fact that the Y gives carbylamine test.

so now from above two points we can conclude that Y is 6 C containing primary amine thus X should contain 7 C atoms.

to check it is aliphatic or aromatic it is given that the Y undergoes coupling reaction this signifies the presence of aromatic ring.

thus formula is C6H5CONH2
