C3H6O did not give a silver mirror with ...

`C_3H_6O` did not give a silver mirror with Tollen's reagent, but gave an oxime with hydroxylamine. It can gove positive

A

iodoform test

B

Fehling's test

C

Schiff's test

D

Carbylamine test

Text Solution

Verified by Experts

The correct Answer is:
A

Since `C_(3)H_(6)O` forms an oxime with hydroxylamine, it must be an aldehyde or a ketone. Since it does not give silver mirror test, it must be a ketone, i.e.,, `CH_(3)COCH_(3)`. Since it is a methyl ketone, therefore, it gives iodoform test.
