Solve this multiple-choice question and choose the correct option.

Organic reaction type (oxime formation): The reaction of an aldehyde with hydroxylamine (e.g., CH3CHO + NH2OH → oxime + H2O) exemplifies which reaction class? Recognize the formation of an oxime with loss of water. Choose the correct option.

Difficulty: Easy

An addition reaction
A condensation reaction
An oxidation reaction
An elimination reaction

Correct Answer: A condensation reaction

Explanation:

Given data

General reaction: R–CHO + NH₂OH → R–CH=N–OH (oxime) + H₂O.

Concept/ApproachThe reaction produces a single product (oxime) with elimination of water, a hallmark of a condensation reaction (specifically, condensation of carbonyl with hydroxylamine).

Final AnswerA condensation reaction
