Does PF5 follow octet rule?
PF5, SF6 and H2SO4 are the examples of expanded octet molecules.
Why does PF5 not follow the octet rule?
Any “extra” bonds are ionic in character with the extra electrons assigned to the outer atoms. In this case, they do not exceed the octet rule. Thus, PF5 has net four covalent bonds and one ionic bond.
Is PCl5 obey the octet rule?
Does PCl5 follow the octet rule? – Quora. No. The P in PCl has 10 valence electrons. The Octet “Rule” is really more of a rule of thumb – and one particularly for organic chemistry at that – than a “rule” rule.
Can KR have an expanded octet?
Two lone electrons form single bond o Expanded Octets ▪ Atoms in 3rd energy level and higher (e.g. P, S, Cl, As, Se, Br, Kr, I, Xe) can accommodate more than 8 electrons (current evidence is that d orbitals are not involved): PCl5, SF6: SF6 can be formed without counting ALL electrons by placing all 6 F atoms around S.
Why does PCl5 break octet rule?
Re: Why does PCl5 break the Octet Rule? Phosphorous, Chlorine, and Sulfur can accommodate more than eight electrons and therefore break the octet rule because they contain a 3d orbital.
Why is PCl5 an exception to the octet rule while PCL3 is not?
Why is PCL5 an exception to the octet rule whereas PCL3 is not? PCL3 every reactant atom follows the octet rule. In PCL5 it is an expanded octet containing ten electrons. Explain the two ways electrons can be shared in a covalent bond.
What violates the octet rule?
The octet rule is violated whenever a bonded atom has either fewer or more than eight valence electrons in its valence shell. The nonmetals after silicon in the Periodic Table can “expand their octet” and have more than eight valence electrons around the central atom.
Can beryllium have an expanded octet?
In some compounds, the number of electrons surrounding the central atom in a stable molecule is fewer than eight. Since beryllium only has two valence electrons, it does not typically attain an octet through sharing of electrons.
