Identify final products in the following sequence of reactions RCOOH + R'OH H ^+ intermediate Ni , ^ H ₂ Products

Options

  1. AR'COOH + RCH ₂ OH
  2. BRCH ₂ OH + R' - OH
  3. CR'CH ₂ OH + R - OH
  4. DR - OH + R' - OH

Correct answer

B. RCH ₂ OH + R' - OH

Step-by-step solution

The first step is the Fischer esterification reaction between a carboxylic acid and an alcohol in the presence of an acid catalyst. The reaction produces an ester as the intermediate. RCOOH + R'OH H ^+ RCOOR' + H ₂ O The intermediate formed is the ester RCOOR' . The second step involves the catalytic hydrogenation (hydrogenolysis) of the ester using hydrogen gas over a nickel catalyst at high temperature. This process cleaves the ester bond, reducing the acyl group ( RCO - ) to a primary alcohol and releasing the a
