Tollen’s test can be used to distinguish

Options

(a) propionaldehyde and acetone
(b) propanol and propionic acid
(c) propene and iso-butene
(d) iso-propanol and propanol

Correct Answer:

propionaldehyde and acetone

Explanation:

Propionaldehyde (propanal) gives silver mirror with Tollens’ reagent. CH₃CH₂CHO + 2[Ag(NH₃)₂]OH → CH₃COONH₄ + 2Ag(silvermirror) + H₂O + 3NH₃.
