Yes you are correct, XeF4 have 2 lone pairs and sp3d2 thus would be in the octahedral arrangement where as SiCl4 does not have lone pairs on the Si thus is a tetrahedral. Just because an atom has 4 attachments does not make it tetrahedral. Dec 23, 2018
The [CoCl4]2 - complex ion is experimentally known to have a tetrahedral structure.

A Shortcut For Determining The Hybridization Of An Atom In A Molecule Look at the atom. Count the number of atoms connected to it (atoms – not bonds!) Count the number of lone pairs attached to it. Add these two numbers together. Jan 16, 2018
Complete answer: -So, the hybridisation of phosphorus is sp3d and the geometry will be trigonal bipyramidal. -Because it has 5 bond pairs and 0 lone pairs. ... -The lone pair will cause the repulsion towards the bond pair and increases the bond angles that's why it is oriented in such a way that it causes less repulsion.
Phosphorus chloride (PCl5)
PCl5 is nonpolar in nature because it has the symmetrical geometrical structure due to which the polarity of P-Cl bonds gets canceled by each other. As a result, the net dipole moment of PCl5 comes out to be zero.
This type of hybridization involves the mixing of one 's' orbital and one 'p' orbital of equal energy to give a new hybrid orbital known as a sp hybridized orbital. ... Each sp hybridized orbital has an equal amount of s and p character, i.e., 50% s and p character.
The following are the rules related to hybridisation: Orbitals of only a central atom would undergo hybridisation. The orbitals of almost the same energy level combine to form hybrid orbitals. The numbers of atomic orbitals mixed together are always equal to the number of hybrid orbitals.
In sp hybridization, one s orbital and one p orbital hybridize to form two sp orbitals, each consisting of 50% s character and 50% p character. This type of hybridization is required whenever an atom is surrounded by two groups of electrons.

POLARITY: POLAR - The lone pair electrons throw off the perfectly cancelling symmetry of the five trigonal bipyramidal regions thus making the overall molecule polar.
Describe why ozone has a bent shape instead of a linear shape. The electron nonbonding domain takes up space, making the molecule bent. Ozone has fewer lone pairs than water, thus a larger angle between bonds. Mar 1, 2020
The reason water has a bent shape is that the two lone pair of electrons are on the same side of the molecule. They really repel each other as they are only attracted to the oxygen atom in the water molecule. Jul 1, 2014

Valence shell electron pair repulsion theory, or VSEPR theory (/ˈvɛspər, vəˈsɛpər/ VESP-ər, və-SEP-ər), is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.
VSEPR is a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom. ... This theory is important because it helps scientists understand the shapes of molecules.

The Lewis electron dot diagram for NO is as follows: ... Boron commonly makes only three covalent bonds, resulting in only six valence electrons around the B atom. A well-known example is BF 3: The third violation to the octet rule is found in those compounds with more than eight electrons assigned to their valence shell.
The two elements that most commonly fail to complete an octet are boron and aluminum; they both readily form compounds in which they have six valence electrons, rather than the usual eight predicted by the octet rule.
We have four bonds, right, and there's two electrons in each. So four times two is eight. So we have eight bonding electrons. Jan 24, 2018

The geometry of molecule of BF3 is 'Trigonal Planar. ' With the reference of Chemistry, 'Trigonal Planar' is a model with three atoms around one atom in the middle. It's like peripheral atoms all in one plane, as all three of them are similar with the 120° bond angles on each that makes them an equilateral triangle. Feb 3, 2021
covalent bond BF3 is a molecule consisting of an sp2 hybrid of Boron covalently bonded with 3 atoms of fluorine. The covalent bond tells us that electrons are shared, rather than lost by boron and gained by fluorine. This bond is formed because of Boron's high ionization energy.
Explanation: Boron has only 3 valence electrons, so when it bonds with F there will only be 3 electron pairs around the boron atom. Repulsion theory predicts that these three e- pairs should find themselves at the vertices of an equilateral triangle (bond angles of 120 degrees). Thus, BF3 is planar triangular. Aug 20, 2020
