Show Answer
Answer:
Correct Answer: A
Solution:
[a] All aldehydes including reducing sugar (as glucose, fructose) gives silver mirror test (with Tollens’ reagent) $ RCHO+2{{[Ag{{(NH_3)}_2}]}^{+}}+3O{H^{-}}\xrightarrow{\Delta } $
$ \underset{Silvermirror}{\mathop{RCO{O^{-}}+2Ag\downarrow }}+4NH_3+2H_2O(R=H,CH_3) $ Thus, acetaldehyde and formaldehyde give silver mirror test.
