Homework Answers
Answer:
The primary force that directs geometry in VSEPR (Valance Shell Electron Pair Repulsion) Theory is Electrostatic Forces.
Why Lone Pair take up more space?
Answer: Electrostatic forces are inversely proportional to the distance between two charged centers. In Lone pairs, the negative charge of 2 electrons (participating in being lone pair) in just accommodated around a single atom and hence the repulsion between participating electrons increase and the size of lone pair is big. On the other hand, in bond pairs, electrons are share on 2 nucleus, so the charge is dispersed and consequently bond pair occupy less space around given atom.

Select all the statements that correctly explain why lone pairs prefer to occupy equatorial positions in a system with five electron domains. Check all that apply. A larger bond angle leads to more electron repulsion. Alone pair in an axial position will be too far away from the other electron pairs. There is less repulsion between electron domains in equatorial positions. Alone pair in an equatorial position has more space. Do you know the answer? Match each molecular geometry correctly...
