We discussed a tetrahedral intermediate in the context of reactions of derivatives of carboxylic acids and nucleophilic substitution reactions. In all of these cases, the tetrahedral intermediate was described as an unstable structure that undergoes subsequent reactions. Briefly explain why tetrahedral intermediates are unstable.

Aldehydes and Ketones

Aldehydes and ketones are organic compounds that have a carbonyl group, C = O, as their functional group. They both differ in the placement of this carbonyl group in their structures.
