Question

The reagents $A$ and $B$ in the reaction sequence are given by the set

• A. Isopropyl alcohol, hydrazine
• B. Isopropyl alcohol, hydroxylamine
• C. t-butyl alcohol, hydrazine
• D. t-butyl alcohol, hydroxylamine

Answer 1

The correct option is C t-butyl alcohol, hydrazine

The reagents A and B in the reaction sequence are given by the set
t-butyl alcohol, hydrazine.
The first reaction is transesterification reaction in which ethoxide group is replaced with t butoxide group.
In the second reaction, ethoxide group is replaced by $-NHN{H}_2$ group.
$C{H}_{3}COO{C}_2{H}_5+(C{H}_3{)}_{3}COH\to C{H}_{3}COOC(C{H}_3{)}_3+C_2{H}_{5}OH$
$C{H}_{3}COO{C}_2{H}_5+N{H}_{2}N{H}_2\to C{H}_{3}CONHN{H}_2+C_2{H}_{5}OH$.
