Question
The diagram represents Miller's experiment. Choose the correct combination of labelling.
Options
A.A–electrodes, B–NH₃+H₂+H₂O+CH₄, C–cold water, D–vacuum, E–U trap
B.A–electrodes, B–NH₄+H₂+CO₂+CH₃, C–hot water, D–vacuum, E–U trap
C.A–electrodes, B–NH₃+H₂O, C–hot water, D–tap, E–U trap
D.A–electrodes, B–NH₃+H₂+H₂O+CH₄, C–steam, D–vacuum, E–U trap
Solution
Sol.(a) [Key Concept: Miller's Experiment — Apparatus Labelling] In Miller's experiment: A = electrodes (providing electrical discharge simulating lightning); B = mixture of gases (NH₃ + H₂ + H₂O + CH₄ — the reducing atmosphere of early Earth); C = cold water (condenser to cool gases); D = vacuum pump; E = U-trap (where condensed organic compounds including amino acids collected). Option (a) correctly identifies all components.
