WebAug 16, 2024 · 1. Phenol reacts with sodium to give sodium phenoxide, liberating hydrogen gas. 2. Phenol reacts with sodium hydroxide to give sodium phenoxide and water. Phenol is more acidic than ethanol. This is because phenol after losing a proton becomes phenoxide ion which is highly stable due to resonance whereas ethoxide ion does not. WebExplanation: In non-polar solvents such as, CS 2 aniline exhibits high resonance due to which it becomes ready to undergo reduction. Due to this the effect of NH 2 attached in the aniline, it gets reduced and a process called mono-substitution takes place in the "para" and "ortho" positions. terrain a vendre lac brome
