Question

An organic compound " P " of molecular formula C_6H_12O_3 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:

Accepted Answer

Correct answer: A. (a) P gives positive iodoform (has CH_3 CO- ) but negative Tollen's (no -CHO). Q (after acid hydrolysis) gives both tests, meaning Q has both CH_3 CO- and -CHO . This indicates P has an acetal protecting an aldehyde group. Option (a): CH_3- CO- CH_2- CH ( OCH_3 )_2 Has CH_3 CO positive iodoform Has acetal - CH ( OCH_3 )_2, no free aldehyde → negative Tollen's Hydrolysis: - CH ( OCH_3 )_2H^+/H_2O- CHO Q= CH_3- CO- CH_2- CHO gives both iodoform and Tollen's test Molecular formula: C_6H_12O_3
