Which from following statements is NOT true for phenol?

Options

  1. APhenols are polar molecules.
  2. BPure phenol is odourless, nontoxic, high melting solid.
  3. CBoiling points of phenols increases with increase in molecular mass.
  4. DPhenols show appreciable solubility in water.

Correct answer

B. Pure phenol is odourless, nontoxic, high melting solid.

Step-by-step solution

Analyzing the properties of phenols: A) Phenols are polar molecules: The hydroxyl group ( - OH ) exhibits significant polarity due to electronegativity differences, resulting in a polar molecule. This statement is true. B) Pure phenol is odourless, nontoxic, high melting solid: While phenol is a solid with a melting point near 40.5^ C , it possesses a distinct carbolic odor and is both toxic and corrosive. Consequently, this statement is not true. C) Boiling points of phenols increase with molecular mass: Enhanced
