In the first reaction, the iodine is replaced by CN so the structure of (A) is CH_{3}CH_{2}CN(propionitrile). On partial hydrolysis, the CN converted into CONH_{2}, So the structure of B is CH_{3}CH_{2}CONH_{2} (propanamide) and the third reactant is Hoffmann bromide degradation reaction, So just remove the -CO group and it becomes a primary aliphatic amine. Thus, the structure of C is CH_{3}CH_{2}NH_{2} (ethanamine)
