Now that it's getting close to Thanksgiving, we're running a contest to hear advice you've received that you're most thankful for! This can be any type of advice and the advice with the most reactions will win!
Yes, CO2 will oxidize Grignard into carboxy acid, where co2 is the source of extra carbon. LiAlH4 is a strong base, it will reduce aldehydes, ketones, carboxy acids and esters into alcohol. However, if you use NaBH4, this only reduces aldehydes and ketones iinto alchohols. Will not reduce acids and esters. Hope this helps.
