Question

Repulsive forces in molecule decreases sharply with: * 1 point A increasing angle between electron pairs B decreasing angle between electron pairs C distance between electrons should be less. D electrons has no role to play

Answer 1

Answer:

Lone pair repulsion: Bond angle is affected by the presence of lone pair of electrons at the central atom. A lone pair of electrons at the central atom always tries to repel the shared pair (bonded pair) of electrons. Due to this, the bonds are displaced slightly inside resulting in a decrease of bond angle.
