Question

If general formula of oxime and semicarbazone is $C = N - Z$, what is ' $Z $ ' in oxime $(I)$ semicarbazone $(II)$ ?

• A. $\overset{I}{NHCONH _{2}} \,\,\overset{II}{OH}$
• B. $\overset{I}{OH}\,\, \overset{II}{NH _{2}}$
• C. $OH NHCONH _{2}$
• D. $NH _{2} OH $

Answer 1

Answer: (C)

Oxime are



Ketox Here, $Z= OH$

Semicarbazone formed by



Here, $Z=- NH - \underset{\overset{||}{O}}{C} - NH _{2}$
