Answer:
The correct answer is C. Repulsion.
When electron groups (such as lone pairs and bonded pairs of electrons) are present in a molecule, they experience repulsion from each other. This repulsion determines the arrangement of these electron groups around the central atom and leads to the formation of bond angles. The repulsion between electron groups is due to the negatively charged electrons repelling each other.
The concept of repulsion between electron groups is explained by VSEPR (Valence Shell Electron Pair Repulsion) theory. According to this theory, electron groups (both bonding and non-bonding) will arrange themselves in a way that minimizes their repulsion, resulting in specific bond angles within the molecule.
Therefore, the correct answer is C. Repulsion.
Answer:
C. Repulsion
Explanation:
The bond angle in a molecule is determined by the repulsion between the electron groups (bonding pairs and lone pairs) around a central atom. Electrons are negatively charged, and like charges repel each other. When there is electron pair repulsion between these groups, it causes them to arrange themselves in a way that minimizes the repulsion, leading to specific bond angles in the molecule. This repulsion determines the geometry of the molecule. Therefore, the correct answer is C. Repulsion.
