Question

Differentiate between Granchaco and Pentanal.​

Answer 1

Answer:

As aldehydes on reacting with tollens reagent gives silver mirror due to the formation of silver PPT.

Here's the reaction I will write it for you in general form

R-CHO + [Ag(NH3)2]OH → Ag +R-COO-NH4+ +H20 +NH3

[Ag(NH3)2]OH is the tollen’s reagent which leads to the formation of Ag that gives us silver mirror.

Ketones do not give this test.

And further you haven't mentioned whether it is pentan-2-one or pentan-3-one.

If it is pentan-2-one then iodoform test can also be applied.

Hope it helps!! :)
