Question

(B) In the boxes below, draw the two self-condensation pro products that result from the mixture in Model 2. Use the roles reagent listed in each box to determine the products. Eation products and two mixed condensation Use the roles (Nu, Ee) for each Self Condensation Nuo = A ΕΦ = A Self Condensation Nuo = B E =B Mixed Condensation NuO = A E = B Mixed Condensation NuO = B ΕΦ = A 5. Mixed condensations can also occur between ketones and aldehydes. (a) Which of the following would be the stronger electrophile? (Circle one) aldehyde / ketone. Explain. (b) in the following reaction explain why benzaldehyde cannot act as a nucleophile. HO o I HOⓇ benzaldehyde H (c) Draw the most likely aldol product of the above reaction.

Answer 1

25 a) Al de hy te is a stronger electrophile because it does not contain any election donating, group but since ketone contain two althy I group do they donate electron density through Inductive and Hyper conjugation Lo decrease electrophile character of Ketone b) dince benzaldehyde do not to abstract by base do a hucheophild. contain cannot any &- Hydrogen act as
