Does PCl5 violate the octet rule?
because it is on the period 3, so it order to have the lowest energy structure, the pcl5 can break the octet rule.
Does chlorine follow the octet rule?
Chlorine has seven valence electrons, so if it takes one it will have eight (an octet). Chlorine has the electron configuration of argon when it gains an electron. The octet rule could have been satisfied if chlorine gave up all seven of its valence electrons and sodium took them.
Why does PCl5 obey the octet rule?
1 Answer. The chlorine atoms obey the octet rule, but the phosphorus atom does not. In a molecule of phosphorus pentachloride, PCl5 , each chlorine atom ends up with an octet of electrons (four pairs), but the phosphorus atom ends up with ten electrons (five pairs).
Is PCl5 expanded octet molecule?
In PCl5, in atomic state P has 5 valence electrons. On sharing 5 electrons with 5Cl atoms, P has total 10 electrons in it’s valence shell. As P has more than 8 electrons in valence shell, it is called as super octet or extended octet.
Which elements are exceptions to the octet rule?
Helium and hydrogen are exceptions to the octet rule, and some say the “duet rule” applies. H and He are stabilized with 2 electrons, not an octet.
Is PCl5 exception of hybridization?
Yes. It is a trigonal bipyramidal molecule. Possesses five bonds. It is a hypervalent stable molecule.
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.
Can chlorine have 14 valence electrons?
Oxygen (group 16) has 6 valence electrons, and chlorine (group 17) has 7 valence electrons; we must add one more for the negative charge on the ion, giving a total of 14 valence electrons.
Can CL have 14 electrons?
Re: Cl as an Expanded Octet However, if you consider it as three double bonds and one single bond, the formal charge of Cl will be 0 and it’ll be more stable. In this case, Cl has expanded its valence shell to 14 electrons.
Which compound does not follow the octet rule?
Solution : `ClF_(3)` does not follow octet rule since the valence shell of the central atom ,i.e., Cl has 10 electrons . Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
Does chlorine form an expanded octet?
Chlorine does not follow the octet rule. It will hold more than 8 electrons. Chlorine having valence electrons in the 3rd energy level, will also have access to the 3d sublevel, thus allowing for more than 8 electrons.
Does Cl have 8 valence electrons?
Cl has 7 valence electrons.
Why does Cl have 7 valence electrons?
Electrons in the outer shells that are not filled are called valence electrons. The atomic number of chlorine is 17. Hence it has got 7 electrons in its outermost shell. There are 7 valence electrons in the chlorine atom.
Which elements can break octet rule?
Hydrogen, beryllium, and boron have too few electrons to form an octet. Hydrogen has only one valence electron and only one place to form a bond with another atom. Beryllium has only two valence atoms, and can form only electron pair bonds in two locations. Boron has three valence electrons.
