Give chemical reactions to show the action of #CO_2# & ethanal on methyl magnesium bromide and methyl lithium?
1 Answer
The metal reagent and carbon dioxide gives a carboxylate salt (a carboxylic acid on work up). With acetaldehyde, a secondary alcohol results.
Explanation:
In fact one of the best ways of making a carboxylic acid is by pouring the Grignard mixture onto dry ice:
The reaction would also occur with methyl lithium.
With acetaldehyde or ethanal,
Note that
