Answer to Question #178446 in General Chemistry for John

Question #178446

1.Briefly describe the preparation of alcohols from ketones, and the preparation of alcohols from esters, each using the same Grignard reagent CH3CH2MgCl. Show an example reaction equation involving your own chosen ketone and ester molecules, respectively, to illustrate your description.(6 marks) 

2.Explain briefly about the oxidation of aldehydes, mentioning suitable oxidation agents that can be used and the reaction conditions needed. Include an example of oxidation reaction equation to illustrate your explanation. (4 marks)

To produce a primary alcohol, the Grignard reagent is reacted with formaldehyde. Reacting a Grignard reagent with any other aldehyde will lead to a secondary alcohol. Finally, reacting a Grignard reagent with a ketone will generate a tertiary alcohol.



Esters can undergo hydride reduction with LiAlH4 to form two alcohols. The alcohol derived from the acyl group of the ester will be 1o and is typically considered the main product of the reaction. The other alcohol is derived from the ester's alkoxy group and is typically considered a side-product of the reaction.
