Step 1: Understanding the reaction sequence 1. Gattermann-Koch reaction:
The first step involves CO, HCl, and CuCl, leading to the formation of benzaldehyde. 2. Cannizzaro reaction:
Strong base (NaOH) induces disproportionation, producing hydroxybenzyl benzoate and sodium benzoate.
In the given circuit, if the potential at point B is 24 V, the potential at point A is:
