Question

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

• A. If both assertion and reason are true and reason is the correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion.
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

Answer: (A)

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