Which of the following species are hypervalent?
1. 2. 3. , 4.
Options:
Answer:
B
Solution:
A species is hypervalent if its central atom expands its octet, meaning it has more than 8 electrons in its valence shell.
AsF₅: Arsenic has 10 valence electrons (5 bonds), making it hypervalent.
SF₆: Sulfur has 12 valence electrons (6 bonds), making it hypervalent.
BF₃ is electron-deficient (6 electrons), and CO₃²⁻ follows the octet rule (8 electrons).
Therefore, the correct option is (B) 1, 3.
