An organic compound " P " of molecular formula 
gives positive Iodoform test but negative Tollen's test. When " P " is treated with dilute acid, it produces " Q ". " Q " gives positive Tollen's test and also iodoform test. The structure of " P " is:
Text Solution
Verified by ExpertsA
P gives positive iodoform (has 
) but negative Tollen's (no -CHO).
Q (after acid hydrolysis) gives both tests, meaning Q has both 
and -CHO .
This indicates P has an acetal protecting an aldehyde group.
Option : 
Has 
positive iodoform
Has acetal 
, no free aldehyde → negative Tollen's
Hydrolysis: 
gives both iodoform and Tollen's test
Molecular formula:
