उत्तर
Assertion is wrong statement but reason is correct statement.
Explanation:
The silver mirror test can be used to determine Tollen's. \[\ce{[Ag(NH2)2]+ OH-}\]. Only aldehydes, not ketones, react with Tollen's reagent to create silver.
A silver mirror test is not given with this affirmative test.
The carbonyl group is present in both aldehyde and ketone.
