Indicate the hybridization of the central atom in (a) H 2 S (b) SeF 6

Hello everyone in this question we're asked to identify the hybridization of the central atom. For each of the molecules, we have a church to l. We have one valence electron for hydrogen. And there's two Plus six valence electrons for oxygen. And this gives us a total of eight. And for the structure we're gonna have oxygen in the center and then two hydrogen atoms coming off of it And each bond contains two electrons. So we have 24 six eight. So I have one two three or electron groups around oxygen. So for the hybridization we're gonna have S Mp three, Our Cl Cl two With four valence electrons for carbon Plus six for oxygen Plus seven for Chlorine. And there's two chlorine And this gives us 24 valence electrons. And for the structure we're gonna have carbon in the center to chlorine coming off of it in a double bonded oxygen. So we have 2468, 10, 12, 14, 16, 18, 20 22, And we have three electron groups around carbon. So our organization is going to be s. p two For XE. F four. We're gonna have eight valence electrons for Xenon Plus seven for Florian. And there's four flooring And that'll give us 36 stainless electrons. And for the structure we're gonna have X. E. In the center and for florian coming off of it We have 2468 10 12 14, 16, 18, 20 22 24 28 30 32 34 and 36. So we're gonna have six electron groups around xenon. So this will give us a hybridization of SP three. Me too. Thanks for watching my video. And I hope it was helpful.

Indicate the hybridization of the central atom in (a) H₂S (b) SeF₆

Verified step by step guidance

Identify the central atom in the molecule SeF6, which is Selenium (Se).

Count the number of atoms directly bonded to Selenium. In SeF6, Selenium is bonded to six Fluorine (F) atoms.

Determine the number of lone pairs on the central atom. Selenium in SeF6 has no lone pairs as it forms six bonds with Fluorine atoms.

Add the number of bonding pairs and lone pairs to find the steric number. For SeF6, the steric number is 6 (six bonding pairs + zero lone pairs).

Use the steric number to determine the hybridization. A steric number of 6 corresponds to sp3d2 hybridization.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Hybridization

Hybridization is a concept in chemistry that describes the mixing of atomic orbitals to form new hybrid orbitals. These hybrid orbitals are used to explain the geometry of molecular bonding. The type of hybridization depends on the number of electron pairs around the central atom, which can include both bonding and lone pairs.

Valence Shell Electron Pair Repulsion (VSEPR) Theory

VSEPR theory is used to predict the geometry of molecules based on the repulsion between electron pairs in the valence shell of the central atom. According to this theory, electron pairs will arrange themselves as far apart as possible to minimize repulsion, which helps determine the molecular shape and the hybridization of the central atom.

Molecular Geometry of SeF6

Selenium hexafluoride (SeF6) has a central selenium atom surrounded by six fluorine atoms. The molecular geometry is octahedral, which indicates that the central atom is hybridized to accommodate six bonding pairs of electrons. This leads to the conclusion that the hybridization of selenium in SeF6 is sp3d2, corresponding to the six equivalent hybrid orbitals formed.
