Question

Assertion (A) : The C―O―H bond angle in alcohols is slightly less than the tetrahedral angle. Reason (R): This is due to the repulsive interaction between the two lone electron pairs on oxygen

Answer 1

ANSWER :

-H in alchols is slightly less than tetrahedral is slightly less than tetrahedral angle (109∘28′). It is due to the repulsion between the unshared electron pairs of oxygen. In alcohols, two lone pair of electrons are present. Therefore, three is comparatively more repulsion and less and angle.
