Card 1
Question: What is the primary model used for predicting molecular geometry?
Answer: Valence Shell Electron Pair Repulsion (VSEPR) theory.
Card 2
Question: What is the fundamental premise of VSEPR theory?
Answer: Electron pairs, whether bonding or non-bonding, repel each other.
Card 3
Question: How do electron pairs arrange themselves around a central atom according to VSEPR theory?
Answer: They arrange themselves as far apart as possible in three-dimensional space to minimize repulsive forces.
Card 4
Question: What is an electron domain in VSEPR theory?
Answer: A region in space where electrons are concentrated, which can be a single bond, a double bond, a triple bond, or a lone pair of electrons.
Card 5
Question: How are multiple bonds treated as electron domains in VSEPR theory?
Answer: A multiple bond (double or triple) is treated as a single electron domain.
Card 6
Question: What is the purpose of electron domains orienting themselves with maximum separation?
Answer: To minimize electron-electron repulsion.
Card 7
Question: What is electron domain geometry?
Answer: It describes the arrangement of all electron domains (bonding and non-bonding) around the central atom.
Card 8
Question: What is molecular geometry?
Answer: It describes the arrangement of only the atoms in the molecule.
Card 9
Question: How do lone pairs influence molecular geometry?
Answer: Lone pairs influence the molecular geometry by taking up space, but they are not considered part of the molecular shape itself. Their presence can lea
Card 10
Question: What are non-bonding electron pairs also known as?
Answer: Lone pairs.
