Which of the following best describes the reduction of a ketone to an alcohol by lithium aluminum hydride (LiAlH4) ?
A) A hydride nucleophile attacks the carbonyl carbon,followed by electrostatic stabilization of the alkoxide oxygen by lithium,followed by acidic protonation of the alkoxide.
B) Lithium aluminum hydride transfers a hydrogen to both the carbonyl carbon and oxygen,resulting in an alcohol.
C) A hydride nucleophile attacks the carbonyl carbon,followed by nucleophilic attack of AlH3 by the generated alkoxide,followed by acidic or basic conversion of the alkoyxaluminum hydride product to an alcohol.
D) Acidic protonation of the carbonyl,followed by neutralization of charge by the ð electrons,followed by nucleophilic attack by hydride.
