Example Question #1 : Ketone Chemistry
What is the product of the reaction between 2-butanone and lithium aluminum hydride?
None of these
Lithium aluminum hydride is a reducing agent. It reduces ketones and carboxylic acids to alcohols. 2-butanone is a 4-carbon chain with a double bond between an oxygen and carbon 2. The reduction turns the double bond with oxygen into a single bond to a hydroxy group. This makes the product 2-butanol.
Example Question #2 : Ketone Chemistry
