X and Y are the reagents needed to change 1-bromopropane into butanoic acid. $\text{CH}_3\text{CH}_2\text{CH}_2\text{Br} \xrightarrow{X} \text{CH}_3\text{CH}_2\text{CH}_2\text{CN} \xrightarrow{Y} \text{CH}_3\text{CH}_2\text{CH}_2\text{CO}_2\text{H}$ What are the correct identities of reagents X and Y?
- A$\text{NH}_3$ ; $\text{HCl(aq)}$
- B$\text{KCN in } \text{C}_2\text{H}_5\text{OH}$ ; $\text{NaOH(aq)}$
- C$\text{KCN in } \text{C}_2\text{H}_5\text{OH}$ ; $\text{HCl(aq)}$
- D$\text{HCN}$ ; $\text{NaOH(aq)}$
