Multiple Choice QuestionsWhich of the following compounds would be the main product of an aldol condensation of acetaldehyde and acetone ?
CH3CH=CHCHO
CH3CH=CHCOCH3
(CH3)2C= CHCHO
(CH3)2C= CHCOCH3
Which one of the following compounds will not react with CH3MgBr ?
Ethyl acetate
Acetone
Dimethyl ether
Ethanol
C.
Dimethyl ether
Grignard reagent (RMgX) reacts with only those compounds which contains acidic hydrogen or which contains carbonyl group.
(c) Dimethyl ether (CH3OCH3)due to absence of both acidic hydrogen and carbonyl group does not react with Grignard reagent.
Hence, CH3MgBr does not react with dimethyl ether.
