CBSE Class 12 · 2018 · Aldehydes Ketones and Carboxylic AcidsShort Answer

Write the structures of the main products of the three reactions shown in the figure.

Solution

The three displayed lines follow standard patterns:
• ester or nitrile + DIBAL-H (one equivalent, low T), then H

_{2}

O → the \textbf{aldehyde};
• a carbonyl + the printed nucleophile (HCN, NH

_{2}

OH, 2,4-DNP...) → the corresponding addition/condensation product;
• side-chain/alcohol + the printed oxidant → the acid or carbonyl.
Match each line and draw its product.
