  1. Question 1

    Q1. The boiling point of phenol is 181.7°C, whereas that of ethanol is 78.3°C. What is the primary reason for this significant difference?

    • A) Hydrogen bonding in phenol
    • B) Polarization of the phenol molecule
    • C) London dispersion forces in phenol
    • D) Intermolecular forces in ethanol

    Answer: Hydrogen bonding in phenol

    Explanation: Phenol forms strong hydrogen bonds, which increases its boiling point compared to ethanol, which has weaker intermolecular forces.
