Fоr the chemicаl reаctiоn belоw, select the аnswer choice that shows all major organic products with the correct stereochemistry. Click to Show Image Description A reaction scheme begins with a carbon double-bonded to oxygen. The same carbon is single-bonded to “Ph” on the left and to a two-carbon chain on the right. A horizontal reaction arrow points to the right. Above the arrow is a nitrogen atom bonded to H and to two separate two-carbon chains, one extending toward the upper left and the other toward the upper right. “pH 5.5” is written below the arrow. No product, lone pairs, charges, solid wedges, or dashed wedges are shown.
