BF3is an electron pair acceptor and completes its octet by accepting:
Correct answer: B. Pair of electrons
- A. An electron
- B. Pair of electrons
- C. 3 electrons
- D. 4 electrons
Explanation
In chemical bonding, an electron pair acceptor is typically referred to as an electron acceptor or Lewis acid. Lewis acids are molecules or ions that can accept a pair of electrons to complete their octet or achieve a more stable electron configuration. BF3, which is boron trifluoride, acts as a Lewis acid and can accept an electron pair from a Lewis base. To complete its octet, BF3 accepts a pair of electrons from a donor species

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
