Answer: 120 degrees.
- A 90 degrees
- B 109.5 degrees
- C 104.5 degrees
- D 120 degrees
Correct answer: D. 120 degrees
Explanation: Three sp<sup>2</sup> hybrid orbitals point to the corners of an equilateral triangle, giving a trigonal planar geometry with 120 degree bond angles.
VSEPR theory predicts molecular shape from the number of bonding and lone electron pairs around the central atom.
Concept context
Understand how atoms join to form molecules. Covers ionic and covalent bonding, VSEPR theory, hybridization (sp, sp², sp³), molecular orbital theory, bond polarity, and intermolecular forces like hydrogen bonding.
