Question

Which of the follwing product is not correct :
Carbonyl compound + Reagent ——→ Product

Answer 1

Answer:

4

Explanation:

semicarbazone would form from semicarbazide , the reagent given in the reaction is urea

Answer 2

Answer:

Explanation:

Concept:

Carbonyl compound + Reagent ——→ Product

Semicarbazide would transform into semicarbazone, with urea serving as the reaction's catalyst.

Semicarbazide is the chemical compound with the

Formula ,

$OC(NH_{2} )(N_{2} H_{3})$

It is a water-soluble white solid. It is a derivative of urea.

Reaction of Semicarbazide :

Semicarbazide is frequently reacted with aldehydes and ketones to produce semicarbazones via a condensation reaction. This is an example of imine formation resulting from the reaction of a primary amine with a carbonyl group.

Reaction of Semicarbazone :

Ammonia derivatives can also be used in lieu of ammonia to produce the comparable derivatives with nitrogen replaced. For instance, hydroxylamine and hydrazine both produce oxime and hydrazone, respectively. Semicarbazone is the end result of adding a semicarbazide to the carbonyl group of ketones or aldehydes.

So that Option 4 is not a following product of Carbonyl compound + Reagent.
