Cho sơ đồ chuyển hóa : \(N{H_2} - CH - COON{H_4}\mathrel{\mathop{\kern0pt\longrightarrow}
\limits_{}^{{\rm{dd}}.NaOH,{t^0}}} X\mathrel{\mathop{\kern0pt\longrightarrow}
\limits_{}^{{H_2}S{O_4}}} Y\mathrel{\mathop{\kern0pt\longrightarrow}
\limits_{_{}}^{C{H_3}OH,{H_2}S{O_4},{t^0}}} Z\)

Biết X, Y, Z đều là các chất vô cơ Chất Z là :
