Chapter 17.SE, Problem 71AP
A problem often encountered in the oxidation of primary alcohols to acids is that esters are sometimes produced as by-products. For example, oxidation of ethanol yields acetic acid and ethyl acetate:

Hydration of aldehydes and ketones can be catalyzed by acid
or base. Bases catalyze hydration by:
protonating the carbonyl oxygen
making the carbonyl group more electrophilic
employing hydroxide ion, which is a better nucleophile than water
making the carbonyl group less electrophilic
shifting the equilibrium position of the reaction to favor products
A synthetic organic molecule, G, which contains both aldehyde and ether functional groups, is subjected to a series of reactions in a multi-step synthesis pathway. In the first step, G undergoes a Wittig reaction, leading to the formation of an alkene, H. Subsequently, H is treated with an ozone (O3) reagent followed by a reducing agent in an ozonolysis reaction, resulting in the formation of two different products, I and J. Considering the functional groups present in G and the nature of the reactions involved, what are the most probable structures or functional groups present in products I and J? A. I contains a carboxylic acid group, and J contains an aldehyde group. B. I contains a ketone group, and J contains an alcohol group. C. I and J both contain aldehyde groups. D. I contains an ester group, and J contains a ketone group. Don't use chat gpt.
The following compounds can exist in both keto and enol forms, but for some of them,
the enol structure is preferred. Please identify which compound in the given list exists
predominantly as an enol form and briefly explain why.
