Vedclass · Accepted Answer

Oximes are less acidic than hydroxylamine.

Vedclass · Answer

(B) Statement $B$ is false because oximes are more acidic than hydroxylamine $(NH_2OH)$.This is due to the delocalization of $\pi$-electrons (resonance) in the conjugate base of the oxime,which stabilizes the negative charge on the oxygen atom.In hydroxylamine,there is no such resonance stabilization of the conjugate base.Statement $A$ is also technically false as both Tollen's reagent and Fehling's solution are used for oxidation,but Tollen's reagent is the standard answer for oxidizing both types of aldehydes.However,in the context of standard chemistry problems,statement $B$ is the intended false statement.
