Question 2 1 pts Which of the following pairs of compounds would give the most successful crossed aldol condensation when combined in the presence of a strong base? (Note: by "successful" we mean that the reaction 1) actually works, and 2) gives only a single aldol condensation product.) masa - marce nie Paic: one and Love Pair o: ¿ and i Оме O

Answer 1

Tage 1 Ans. In the given question it is asked that .cokich oĚ the following pars ef_compounds would give the most successfulcused' -afdal condensation when combined in presence of strong base for this reaction should >_estually works! a gives_only a single aldone- condencation 2 * for this purpose let us first see what is Cossed alcol condensation reaction ? In a crossed aldol reaction two different caobonyl compounds are applied. If bitte 1 carbonyl_compound contains & hydrogen. Fatom, both may act an electrophillic carbonyl compound, as well as mucleophillic enolovs cholate As result such a crossed aldol reaction yields four different product, *Hence the basic condition for oldal reaction There should be Q_hycloogen in the -casbonyl compounde & To our case U A Part B HAH and ph Contains_NO hydrogen thus this option can be easily eliminated foom the discuss joj E Now lets proceed further canned with CamScanner

that Di SD 2 will give 4 Poseduce as 31 cause both the reactants conteeins o hydrogen chence there will be crossed aldol reaction with four product Rok them will form by sell al do condensent t and a will tom by cursed reaction E x hydoogensen cs Scanned with Campcanner

tenic groups CH3 90-9344 No a-hydrogen 4-hydrogen tNow although there is a bydlingen present in and reactant due to sterica I crocoding tert-butyl group virtually never I reacts with other reactant and with itself also hence celdol condensation doein't takes place - This which our correct option gives only one is Part 6 product as Thank you las Scanned with Carp Scanner
