Suggest a possible identity for each of the reagents L, M and N.
Give the structure of the organic product obtained when M reacts with butanal.
What is seen when N reacts with butanone?
What type of reaction occurs when N reacts with butanone?
The organolithium compound methyl lithium, $\text{CH}_3\text{Li}$, can supply $\text{CH}_3^-$ ions: $\text{CH}_3\text{Li} \rightleftharpoons \text{CH}_3^- + \text{Li}^+$. The $\text{CH}_3^-$ ion can act as a nucleophile. Suggest a mechanism for the reaction of butanal with $\text{CH}_3^-$ ions. Include every necessary curly arrow, lone pair and relevant dipole.
A chemist plans to make the following organic compound G from butanal. Draw the structure of the organolithium reagent that could be used to prepare G from butanal.
