Solution
The correct option is B A-Ethanal, X-Ethanol, Y-But-2-enal, Z -Semicarbazone
C2H6O could be dimethyl ether, ethylene oxide or ethanol. But the reaction with Cu at 573 K all but confirms that the substrate is in fact, ethanol C2H5OH, which gets oxidized by cupper dust to ethanol. So A is ethanal (A), which shows a positive Tollen’s reagent test.
A - acetaldehyde, undergoes aldol condensation to yield but-2-enal - the α−β unsaturated aldehyde. Also, A reacts with semicarbazide to give an imine called - semicarbazone (this is not a specific compound, it is a class of imine).
