Question

Which of the following reactions would not normally yield an alcohol? A. Oxymercuration/ de mercuraction of alkenes B. Hydroboration of alkene C. Reaction of a carboxylic acid with NaBH4 D. Reaction of ketone with a Grignard reagent

Answer 1

The reaction which normally would not yield an alcohol is → B) Hyderdonation of alkene Because, after hydroboration of the alkene the reach should be followed by oxidation to get alcohol. R-Clache_Bit RCH-CH2 ->, (R-CH2-ChatyB 4.- Biz oxidation (12.2010 H ---Bity onidation R-CH-CH₂-OH. The best reagent to perform the reaction is → A) PCC; CH 3 Mg Br; Pollzlly Pyridine (dehydration) 1 excess Li Alte HO 2 H30 HO Because, at normal temp. double is not reduced by La Alta.
