NEET2016ChemistryChemical Bonding and Molecular StructureActual

Assertion : bond angle is less than the normal tetrahedral bond angle. Reason : Lone pair-lone pair repulsion decreases bond angle.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

The bond angle in alcohols is slightly less than the tetrahedral angle 109^ 28^ due to repulsion between the unshared electron pairs of oxygen.
