Three constitutional isomers of molecular formula C 5H 8O can be converted to 1-pentanol (CH 3CH 2CH 2CH 2CH 2OH) on treatment with two equivalents of H 2 in the presence of a Pd catalyst. Draw the structures of the three possible compounds, all of which contain a carbonyl group
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.
When A is reacted with hot aqueous NaOH, a compound B of molecular formula C8H11NO is produced. With this information, write the correct structure of B and propose the reaction mechanism (step by step, with the correct use of arrows) to obtain B.
