Answer: 5 sigma and 1 pi.
- A 5 sigma and 1 pi
- B 4 sigma and 2 pi
- C 6 sigma and 0 pi
- D 3 sigma and 2 pi
Correct answer: A. 5 sigma and 1 pi
Explanation: Ethene has four C-H sigma bonds plus one C-C sigma bond (5 sigma) and one C-C pi bond, so 5 sigma and 1 pi.
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.
