- (a) Give an acceptable name for compound A. (b) Draw the organic products formed when A is treated with each reagent: [1] H3O+; [2] −OH, H2O; [3] CH3CH2CH2MgBr (excess), then H2O; [4] LiAlH4, then H2O.arrow_forwardDraw the product formed when (CH3)2CHOH is treated with each reagent (d, e and f)arrow_forwardEthers are oxidized with O2 to form hydroperoxides that decompose violently when heated. Draw a stepwise mechanism for this reaction.arrow_forward
- Draw the product formed when (CH3)2CHOH is treated with each reagent (a, b and c)arrow_forwardProcyclidine is a drug that has been used to treat the uncontrolled body movements associated with Parkinson’s disease. Draw three different methods to prepare procyclidine using a Grignard reagent.arrow_forwardDraw the products formed when A or B is treated with each reagent. In some cases, no reaction occurs.a.
