(b) How do the valence orbitals (3s, 3px, 3py, 3pz) on the central P atom transform in this point Aug 23, 2019 · As important and useful as the octet rule is in chemical bonding, there are some well-known violations. CS2 c. Reason: Octet rule is not applicable to the second period elements of the periodic table. 0k points) Octet Rule: Octet rule is violated by expanded shell molecules and electron-deficient species. The three are odd-electron molecules, electron-deficient molecules, and expanded valence shell molecules. Adding two positive integ For a chlorine atom to become a chloride ion, it must gain an electron. Calculate the formal charge for F in PF5. Apr 10, 2023 · Three cases can be constructed that do not follow the octet rule, and as such, they are known as the exceptions to the octet rule. There are mainly three limitations of the octet rule: Aug 13, 2019 · As important and useful as the octet rule is in chemical bonding, there are some well-known violations. CF4 C. B F 3 does not follow octet rule because central boron atom is surrounded by 6 electrons. Is the octet rule obeyed in these cases? asked Jan 27, 2020 in Chemistry by SurajKumar ( 64. To fill the outer electron shells of both atoms. However, there are some exceptions to this rule, and BF3 is one of them.
