The hydroxyaldehyde shown cyclizes to form a hemiacetal under acidic or basic conditions. Use wedge- dot structures to draw the two stereoisomers formed from the aldehyde when it cyclizes. Explain if the relationship between the products. Is the product mixture expected to be optically active or optically inactive? HOH H3C-©CH2CH2C

QUESTION 1 Any reaction involving a carbonyl group and a strong acid begins with the same first step, which is __________________ of the carbonyl oxygen. QUESTION 2 Using condensed molecular formulas (C#H#X#Y#) for your answers, predict the products of the reactions of C6H5CH2CHO (phenylacetaldehyde) with these reagents, and identify the functional group produced in the product. Note that the Tx symbol above allows you to do a subscript. a. NaBH4 / CH3OH b. 1. CH3MgBr; 2. H2O c. Ph3P=CHCH3 d....

Assume that the compound depicted above was formed under acidic conditions, was the major product obtained after purification (> 70%), and was isolated as a mixture of diastereomers. Is it possible to know with absolute certainty that the immediate precursor featured the 6-membered ring that is seen in the product? Indicate your answer by circling the appropriate word below. YES NO Explain your reasoning. Your answer should contain sufficient detail to persuade a scholar of organic chemistry. The best answers...
