Identify the major product C formed in the following reaction sequence:${\text{CH}}_3{\text{CH}}_2{\text{CH}}_2\text{I}\stackrel{\text{NaCN}}{\to }A\stackrel{\text{Partial Hydrolysis}}{\to }B\stackrel{{\text{NaOH, Br}}_2}{\to }C$

1. $\text{NaCN}$: Nucleophilic substitution ($S_{N}2$) converts $1^{\circ }$ iodide to nitrile. ${\text{CH}}_3{\text{CH}}_2{\text{CH}}_2\text{CN}$ (Butanenitrile). (A).2. Partial Hydrolysis: Converts nitrile to amide. ${\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CONH}}_2$ (Butanamide). (B).3. ${\text{NaOH, Br}}_2$: Hofmann Bromamide Degradation. Converts an amide to an amine with one less carbon.${\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{CONH}}_2\to {\text{CH}}_3{\text{CH}}_2{\text{CH}}_2{\text{NH}}_2$ (Propylamine). (C).
