Identify the product in following reaction. Pent - 3 -enenitrile $\xrightarrow[\mathrm{H}_3 \mathrm{O}^{+}]{\mathrm{AlH}(-\mathrm{Bu})_2}$ product
  1. Pent-3-en-1-amine
  2. Pentanal
  3. Pent-3-enal
  4. Pent-3-en-1-ol

Solution

$\underset{\text{Pent-3-enenitrile}}{\mathrm{H}_3 \mathrm{C}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_2-\mathrm{C} \equiv \mathrm{N}} \xrightarrow[\mathrm{H}_3 \mathrm{O}^{+}]{\mathrm{AlH}(i-\mathrm{Bu})_2} \underset{\text{Pent-3-enal}}{\mathrm{H}_3 \mathrm{C}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_2-\mathrm{CHO}}$ $\mathrm{AlH}(\mathrm{i}-\mathrm{Bu})_2$ acts as a reducing agent.
