Question

Which one of the following violates the octet rule?
1 point
NF3
OF2
CBr4
AsF5​

Answer 1

Answer:

There are three violations to the octet rule: odd-electron molecules, electron-deficient molecules, and expanded valence shell molecules.

Answer 2

Answer:

Explanation:

Octet Rule Definition:

The octet rule describes atoms' preference for having eight electrons in their valence shell. Atoms with fewer than eight electrons are more likely to react and create stable compounds.

• The noble gas configuration of arsenic is$[Ar]4s 2 3d 10 4p 3.$
• There is a 4d orbital that is empty.
• These vacant orbitals could be implicated in the hybridization process, resulting in an extended octet for these core atoms.
• As a result,AsF5​ breaks the octet rule.
